Magnetic field square loop
WebShow Solution. Calculate the magnetic field strength needed on a 200-turn square loop 20.0 cm on a side to create a maximum torque of 300 N ⋅ m if the loop is carrying 25.0 A. Since the equation for torque on a current-carrying loop is τ = NIAB sin θ, the units of N ⋅ m must equal units of A ⋅ m 2 T. Verify this. WebQuestion: A square wire loop with 2.1 m sides is perpendicular to a uniform magnetic field, with half the area of the loop in the field as shown in the figure. The loop contains an ideal battery withemf ε−20 V. If the magnitude of the field varies with time according to B −0.035 T−(0.82 T/s)t, with B in teslas and t in seconds, what are (a) the net emf in the circuit
