A0.8 m length of wire is formed into a single turn, square loop in which there is a current of 12 a. the loop is placed in magnetic field of 0.12 t, which is perpendicular to a normal to the loop plane. what is the maximum torque that the loop can experience?

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.
