The maximum force measured on a 3.72 m wire is 0.731 n when the magnetic field is 0.093 t. what current flows through the wire? o 2.36 a o 225a o 2.11 a o 218

Current, I = 2.11 A

Explanation:

It is given that,

Length of the wire, L = 3.72 m

Maximum force on the wire, F = 0.731 N

Magnetic field, B = 0.093 T

We have to find the current flowing the wire. The force acting on the wire is given by :

When , F = maximum

So,

I = 2.11 A

So, the current flowing through the wire is 2.11 A. Hence, the correct option is (c).

we need to know the time interval during which the force acts. impulse of force = momentum change
