Question

On what factors does the magnetic field strength of a current-carrying coil depend?

Answer 1

1. A current coil is a coil having current in it.
2. When the current is passed through it, the magnetic field is produced around it.
3. It simply works on the principle of the magnetic effect of current.
4. A current-carrying coil may be of any shape like a circular or spiral shape.

Magnetic field due to current carrying coil depends on,

1. Magnetic field due to current carrying coil is directly proportional to the current in the coil.
2. Magnetic field due to current carrying coil is inversely proportional to the radius of the coil.
