A long, straight wire carries a current and lies in the plane of a rectangular loop of wire, as shown in the figure. Determine the maximum emf, |E|, induced in the loop by the magnetic field created by the current in the straight wire. Answer in units of mV.
A conducting loop in the shape of a square of edge length I = 0.400 m carries a current I = 10.0 A as shown in Figure P30.5. Calculate the magnitude and direction of the magnetic field at the center of the square.
(b) What if? If this conductor is reshaped to form a circular loop and carries the same current, what is the value of the magnetic field at the center?
Acircular wire loop has radius R = 0.161 m and carries current i =0.285 A. The loop is placed in the xy-plane in a uniform magneticfield pointing in the negative z direction with magnitude 3.67 T,as shown in the figure.a) Determine the magnitude of the loopâs magnetic moment.b) Calculate the potential energy of the loop in the positionshown.
