Awire 50 cm long with an east-west orientation carries a current of 7.0 a eastward. there is a uniform magnetic field perpendicular to this wire. if the force on the wire is 0.5 n upward, what are the direction and magnitude of the magnetic field?

The magnetic field is 0.143 T in north direction.

Explanation:

Given that,

Length = 50 cm

Current = 7.0 A

Force = 0.5 N

We need to calculate the magnetic field

Using formula of magnetic force

The direction of the magnetic field toward north.

Hence, The magnetic field is 0.143 T in north direction.
