What will happen when the magnet moves towards the coil?

What will happen when the magnet moves towards the coil?

When a magnet is moved towards the coil then a current is induced in the coil due to the phenomenon of electromagnetic induction. Due to the relative movement between the magnet and the coil an electromotive force (EMF) is induced which in turn causes the current in the coil.

What is the direction of the current induced in the coil?

The current induced in the coil creates another field, in the opposite direction of the bar magnet’s to oppose the increase. This is one aspect of Lenz’s law—induction opposes any change in flux.

What is the direction of current in a bar magnet?

Because like magnetic poles repel each other, Lenz’s law states that when the north pole of the bar magnet is approaching the coil, the induced current flows in such a way as to make the side of the coil nearest the pole of the bar magnet itself a north pole to oppose the approaching bar magnet.

When north pole of the bar magnet is inserted into the coil towards which direction does the galvanometer deflect and why?

When we insert the north pole (N) of bar magnet into the coil, the needle gets deflected in negative direction.

Why current flows in a coil when a magnet is pushed in and out of the coil?

When we induce a current in the coil, it becomes an electromagnet. One end of the coil is a north pole and the other end is a south pole. When we pull the magnet out, the left hand end of the coil becomes a south pole (to try and hold the magnet back). Therefore the induced current must be flowing clockwise.

Why the coil rotates when there is a current in the coil?

The coil of wire is mounted in the gap between the two magnets. The split rings make electrical contact with the coil and reverse the current every half turn. When an electric current flows through the coil, a force is exerted on the coil, causing it to spin.

What is the direction of the current induced in coil 2 if the current in coil 1 increases?

Since the resultant magnetic flux in the coil 2 due to coil 1 is into the plane of the coil, as current in the coil 1 increases, the induced current in the coil 2 will be to oppose the flux due to coil 1. Hence the direction of the induced current in the coil 2 will be counter clock wise.

How does the current change as the magnet approaches the loop?

As the magnet approaches the coil of wire, the magnetic field approaches. The stationary coil experiences an increasing then decreasing magnetic field, which induces an electric field in the stationary frame of the coil. thus current, or induced electricity.

What happens as you move the north side of the magnet into the coil?

By using Lenz’s Law. When we induce a current in the coil, it becomes an electromagnet. When the north pole of our magnet is moving towards the left hand end of the coil, the induced current flows anticlockwise (as we look at the left hand end). This makes the left hand end of the coil into a north pole.

When the north pole of a bar magnet is pushed towards the coil?

When the North-pole of a bar magnet is pushed towards the coil, the pointer in the galvanometer deflects, indicating the presence of electric current in the coil.

When north pole approaches a coil the front side of coil?

Answer: When North pole approaches a coil, the front side of the coil will show an anticlockwise current.
