Question

A current carrying loop is coplanar with a long infinite current carrying wire as shown in the figure. If the loop is now rotated about axis XX" by an angle of 120° The final flux of magnetic field associated with the loop will be -
​

Answer 1

The loop carries current as:

Explanation:

• A loop can carry 3600 amps of current.

• At each point of a current-carrying circular loop, the magnetic field lines are concentric circles. The right-hand thumb rule can be used to determine the direction of the magnetic field in each part of the circular loop.

• The magnetic field lines are straight at the centre of the circular loop.

• Within the loop, each section of a circular loop carrying current generates magnetic field lines in the same direction.

• The magnetic field at the centre of the circular coil is perpendicular to the coil's location, i.e. it runs parallel to the coil's axis.
