What is the direction of a magnetic field at a point?
(a) The direction of magnetic field at a point is taken to be the direction in which the north pole a magnetic compass needle points.
How is the direction of the magnetic field at a point in space related to the magnetic field line at that point?
The direction of the magnetic field is tangent to the magnetic field line at any point in space. The strength of the magnetic field is visualized by the closeness of the lines to each other. It is proportional to the number of lines per unit area perpendicular to the lines.
Which direction should magnetic field lines be drawn?
The lines are drawn from the north pole of one magnet to the south pole of the other. The direction, as always for magnetic field lines, is away from the north toward the south.
What is the direction of the magnetic field at a point outside the surface of the loop?
For the point outside the surface of the loop the direction is outwards (going outside of the plane).
Why the direction of magnetic field is from north to south?
When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole.
What is the direction of magnetic field lines inside any magnet?
Inside the magnet, the direction of field lines is from its south pole to its north pole. Thus the magnetic field lines are closed curves.
Do magnetic field lines always go from north to south?
Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.
What is the direction of field lines?
The lines are directed from north pole to the south pole outside the magnet while they are directed from south pole to north pole inside the magnet. A tangent drawn on a magnetic field line gives the direction of the magnetic field at that point. The direction can also be determined by using a magnetic compass.
What is the direction of the magnetic field at a point on the axis of current carrying circular coil?
The direction of magnetic field depends upon the direction of current passing through that circular loop . If the current is flowing clockwise then the direction of magnetic field is inside the loop along the axis and vice versa.
How do you determine the direction of a magnetic field in a loop?
The direction of magnetic field of every section of the circular loop can be found by using the right hand thumb rule.
- At the centre of the circular loop, The magnetic field lines are straight.
- Each segment of circular loop carrying current produces magnetic field lines in the same direction with in the loop.
Do magnets always point north?
Importance of Magnetic Poles This is called the north-seeking pole of the magnet, or simply the north pole. The opposite end is called the south pole. The needle of a compass is itself a magnet, and thus the north pole of the magnet always points north, except when it is near a strong magnet.
Why magnets always have a north and south pole?
The total effect is to make a huge magnetic field that points (approximately) in the northern direction. Taking these two ideas together, then, the Earth's magnetic field will cause the magnet to align north to south. That's why people named them the north and south poles.
In what direction will magnetic field inside a bar magnet point?
(i) The direction of magnetic field lines inside a bar magnet is from its south pole to its north pole.
Why do magnets always point north and south?
Answer: Solution: A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction.
Why does compass always point north?
Earth's south magnetic pole is near Earth's geographic north. Earth's magnetic north pole is near Earth's geographic south. That's why the north pole of a compass points toward north because that's where Earth's south magnetic pole is located and they attract.
Is magnetic field directed from north to south?
The direction of the magnetic field lines is the direction of the B-field. By convention they go from North to South.
What is the direction of magnetic field inside the circular loop?
The direction of magnetic field depends upon the direction of current passing through that circular loop . If the current is flowing clockwise then the direction of magnetic field is inside the loop along the axis and vice versa.
What is the direction of magnetic field at a point outside the surface of the loop?
For the point outside the surface of the loop the direction is outwards (going outside of the plane).
What is the direction of magnetic field outside the circular loop?
According to right-hand rule, the direction of magnetic field inside the loop will be pointing downward. Outside the loop, the direction of the magnetic field will be upward.
Do All magnets have north and south?
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.
Do magnetic fields always go from north to south?
Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.
What is the direction of a magnetic field lines inside any magnet?
Inside the magnet, the direction of field lines is from its south pole to its north pole. Thus the magnetic field lines are closed curves.
Why does a magnet always point north?
When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole.
Why does magnetic field go from north to south?
When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole.
What is the direction of the magnetic field lines outside any magnet?
The direction of magnetic field lines outside a magnet is from the North Pole to the South Pole.
Is north positive or negative?
When magnets are used in magnetic therapy, the poles are often referred to as being positive or negative. Generally, the south pole is termed positive, and the north negative.
What is the direction of magnetic field inside and outside the loop?
According to right-hand rule, the direction of magnetic field inside the loop will be pointing downward. Outside the loop, the direction of the magnetic field will be upward.
