Problem

A straight conductor

0.30\,\text{m}

long carries a current of

10\,\text{A}

and is perpendicular to a uniform magnetic field of

0.40\,\text{T}

. a. (i) Calculate the magnetic force on the conductor. b. (ii) The conductor is now rotated so that it makes an angle of

45^{\circ}

with the magnetic field. What current must flow through it so that the magnitude of the force remains the same as in part (i)?
