d ed A loop of wire with radius r =0.065 m is placed in a region of uniform magnetic field with magnitude B. As shown in the figure, the field direction is perpendicular to the plane of the loop. The magnitude of the magnetic field changes at a constant rate from B? 0.25 T to B? =5.5 T in time At =2.5 s. The resistance of the wire is R11 Q2. 13% Part (a) Enter an expression for the magnitude of the magnetic flux through the loop using the symbols in the palette below.
