Question

A copper wire with density ρ = 8960 kg/m3 is formed into a circular loop of radius 50.0 cm. The cross-sectional area of the wire is 1.00 x 10^-5 m², and a potential difference of 0.0120 V is applied to the wire. What is the maximum angular acceleration of the loop when it is placed in a magnetic fieldof magnitude 0.250 T? The loop rotates about an axis in the plane of the loop that corresponds to a diameter.

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
