Apotential difference of 35 mv is developed across the ends of a 12.0-cm-long wire as it moves through a 0.27 t uniform magnetic field at a speed of 4.0 m/s. the magnetic field is perpendicular to the axis of the wire. part a what is the angle between the magnetic field and the wire's velocity?

Angle between the magnetic field and the wire's velocity is 15.66 degrees.

Explanation:

It is given that,

Potential difference or emf, V = 35 mV = 0.035 V

Length of wire, l = 12 cm= 0.12 m

Magnetic field, B = 0.27 T

Speed, v = 4 m/s

We need to find the angle between the magnetic field and the wire's velocity. We know that emf is given by :

So, the angle between the magnetic field and the wire's velocity is 15.66 degrees.
