Question

(a) Draw the magnetic lines of force due to a circular wire carrying current.
(b) What are the various ways in which the strength of magnetic field produced by a current-carrying circular coil can be increased?

Answer 1

Answer:

a) the above diagram

B) by increasing the no. of turns of coil.

by increasing the magnitude of current in cool.

Answer 2

Explanation:

(a) When current flows via a circular wire it produces a magnetic field around it. The lines of the magnetic field are circular to the wire. These lines are linear at the centre.  The magnetic lines of force due to a circular wire carrying current is shown in the attachment.

(b) Ways of increasing the strength of the magnetic field generated by a circular coil that carries current are as follows

  1. By increasing the current which passes through the wire

  2. By reducing the coil radius

  3. By increasing the size of wire spins inside the coils
