Which magnetic effect is the weakest?
The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet. The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet.
Which magnet is the weakest magnet?
Bar Magnets Bar Magnets The north pole of one magnet attracts the south pole of another magnet. A bar magnet is considered as the weakest magnets because the poles have the smallest area.
Which part of a magnet has the strongest magnetic effect?
It is strongest at the poles. So, what are magnetic poles? Magnetic poles are opposite ends of a magnet where the magnetic field is strongest.
Which part of the magnet has the least magnetic power?
middle surface The magnetic power is highest at the north and south poles whereas it is least at the middle surface of the magnet this is because the magnetic field lines are minimum at the middle surface. Denser the magnetic field lines more are the magnetic power.
Why is magnetic strength more at the poles?
As the distance from the pole increases, the density of magnetic force of lines decreases. Hence magnetic force of lines are more crowded at the poles compared to the centre of magnet and hence strength of magnetic field at north and south pole magnet is more compared to centre of magnet.
Why magnetic field strength is more at poles?
The magnetic field around a solenoid depends on core, turns and current. For a magnet, the flux lines repel each other so the field will be weaker at the sides. But they are concentrated at the poles, where they originate, so the field is stronger.
Where is the magnetic field weakest?
Intensity: The magnetic field also varies in strength over the earth's surface. It is strongest at the poles and weakest at the equator.
Why is the magnetic field stronger at the pole?
The magnetic field around a solenoid depends on core, turns and current. For a magnet, the flux lines repel each other so the field will be weaker at the sides. But they are concentrated at the poles, where they originate, so the field is stronger. Air is a poor conductor of flux.
Which part of the magnet is strongest pole or the body?
The strongest part of a magnet is the magnetic pole. It's important to understand that magnets are made up of two parts, the north, and south poles.
What is magnetic pole strength?
Definition of pole strength : a quantity corresponding to the amount of magnetic flux emanating from a given magnetic pole and expressed in terms of the unit magnetic pole.
Which magnet is the strongest?
Neodymium magnets Neodymium magnets are by far the strongest type of permanent magnet available.
Where is magnetic field weakest?
Intensity: The magnetic field also varies in strength over the earth's surface. It is strongest at the poles and weakest at the equator.
Which refers to the ends of a magnet where the forces are strongest?
Magnetic Pole. The ends of a magnetic object, where the magnetic force is strongest. Any magnet, no matter what its shape, has two ends, each one called a magnetic pole. The magnetic effect of a magnet is strongest at the poles.
How does the pole strength and magnetic moment?
Pole strength of a magnet is defined as the strength with which the materials get attracted towards the magnet. It is the scalar quantity and is represented by the letter m. The magnetic moment is the product of the pole strength and the length of the magnet.
What does pole strength depend on?
(iv) Pole strength of the magnet depends on the nature of material of magnet and area of cross section. It doesn't depends upon length. (i) It is a vector quantity directed from south to north.
Where is the magnetic field weakest in a solenoid?
the center The magnetic field is weakest at the center and strongest between the two poles just outside the bar magnet.
What is the magnetic strength at the pole?
Solution. The magnetic strength is maximum at the poles.
How does the pole strength and magnetic moment of each part of the bar magnet change if it is cut into two equal pieces along its length?
The pole strength remains unchanged ( since pole strength depends on number of atoms in cross-sectional area).
Is magnetic field strongest in a solenoid?
Answer and Explanation: The magnetic field is strongest inside the coil of a solenoid. Inside the coil of a solenoid the magnetic field lines are uniform and tightly packed…
How does the pole strength and magnetic moment of each part of a bar magnet change?
(i) The pole strength remains unchanged (since pole strength depends on number of atoms in cross-sectional area). (ii) The magnetic moment is reduced to half (since M ∝ length and here length is halved).
How does the pole strength of each part of bar magnet?
2l` <br> If the magnet is cut along its length into two equal parts , pole -strength of each part ,the number of free poles of the molecular magnets at it extremities will also be halved . . <br> So , the pole – strength of each part =`(m)/(2)` and magnetic length = 2l .
Where is the magnetic field weakest in a bar magnet?
the center The magnetic field is weakest at the center and strongest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.
Why magnetic field is stronger near the poles?
The closer the magnetic field lines are, the stronger the magnetic field at that point. As we can see in the diagram, the magnetic field lines are closer or denser at the poles. So, the magnetic field is strongest around the poles of the magnet.
How does the pole strength and magnetic moment of each part of bar magnet change if it is cut into two equal pieces transverse to its length?
The pole strength remains unchanged ( since pole strength depends on number of atoms in cross-sectional area).
How does the pole strength and magnetic moment of each part of a bar magnet change if it is cut into two pieces along with its length?
<br> When we cut along the length, pole strength of each new magnet is half the pole strength of original magnet , magnetic moment is also halved, as length remains the same.
How does the pole strength and magnetic moment of each part?
How does the (i) pole strength and (ii) magnetic moment of each part of a bar magnet change if it is cut into two equal pieces along its length? Each piece is a magnet with reduced pole strength and reduced magnetic moment. (i) Pole strength of each new magnet becomes half of original magnet.
Why magnetic field is weakest at Centre?
For a point near the centre of the bar, the magnetic field is very small because the contributions of the nearest magnetic dipoles (tiny magnetic bars) is partially cancelled by the rest of the dipoles because its contribution is anti-parallel.
Where is Earth’s magnetic field the weakest?
the equator The intensity of the magnetic field is greatest near the magnetic poles where it is vertical. The intensity of the field is weakest near the equator where it is horizontal. The magnetic field's intensity is measured in gauss. The magnetic field has decreased in strength through recent years.
How does the pole strength and magnetic moment of each part of a bar magnet change if it is?
How does the (i) pole strength and (ii) magnetic moment of each part of a bar magnet change if it is cut into two equal pieces along its length? Each piece is a magnet with reduced pole strength and reduced magnetic moment. (i) Pole strength of each new magnet becomes half of original magnet.
Why is the magnetic field weaker?
Earth's magnetic field, which protects it from solar radiation, has a weak spot that's expanding. This weak spot may be caused by pieces of an ancient planet that hit Earth and sank into the mantle. The growing "dent" in the magnetic field can cause malfunctions in satellites and spacecraft.
