A stragiht conductor carrying current `I_1` is passed along the axis of a circular conductor carrying current `I_2`. With what fore are the currents interacting?

Two long wires carrying current I_1 and I_2 are arranged as shown in figure. The one carrying current I_1 is along the x-axis. The other carrying current I_2 is along a line parallel to the y-axis given by x=0 and z=d. Find the force exerted at O_2 because of the wire along the x-axis.

Derive an expression for the force between twolong parallel conductors carrying current in the same direction.What type of force is acting between two long parallel conductors carrying current in the same direction ? Using the expression define S.l. unit of current.

A conductor carrying current is placed somewhere. What is the magntiude and direction of the field due to a small part of the conductor at a point near it?

The magnetic lines of force around an infinitely long conductor carrying current are:

WHat is the direction of force between two parallel conductors carrying current in same direction

An electron is moving with velocity vecv along the axis of a long straight solenoid carrying current 'I'. What will be the force acting on the electron due to the magnetic field of the solenoid?

Fill ups ……………….established in 1820 that a conductor carrying current produces a magentic field around it.
