A0.2 kg conductor of length 0.8 m carries 2 ampere current to the right in a magnetic field. what is the magnitude and the direction of the magnetic field acting on the conductor if the net force on the rod is zero? (assume that the rod is hung by two insulating supports.)

The magnetic field is 1.23 T in upward.

Explanation:

Given that,

Mass = 0.2

Length = 0.8 m

Current = 2 A

We need to calculate the magnetic field

If the net force on the rod is zero so the magnetic field is equal to the weight.

Using formula of magnetic force

Put the value into the formula

For direction, using right hand rule

In right hand rule, Thumb represents the force, forefinger represents the magnetic field and the middle finger represents the current.

So,

The direction of the magnetic field is upward.

Hence, The magnetic field is 1.23 T in upward.
