a) The magnetic field is a certain region varies with time given by B(t) =30e^ -2t in Tesla. A 10cm * 15cm rectangular coil whose plane is perpendicular to the direction of the magnetic is placed in this field, find the magnetic flux as a function of time flux(t). b) A coil consists of 200 turns of wire. Each turn is a square of side d=18cm, and a uniform magnetic field directed perpendicular to the plane of the coil is...
A magnetic B field of strength 16 T is perpendicular to a conducting loop of wire measuring 0.6 square meters with 40 turns. If the B field is linearly reduced to zero in 6 s, then what is the magnitude of the induced emf voltage?
3. Electromagnetic Inductance. Consider a single loop under magnetic field. (a) If the area A = 0.012[m) is constant, but the magnetic field is increasing at the rate of 0.020 T/s), determine the induced emf. (Use Faraday's law; the induced emf in a loop equals the absolute value of the time rate of change of the magnetic flux through the loop.) (b) If the total resistance of the circuit is 5.0(82), find the induced current. (c) Suppose we change the...

The circular top portion of the circuit in the image below lies
in a uniform magnetic field of magnitude B and directed out of the
plane of the screen. The loop is pulled as shown so that its area
decreases. The decreased area is indicated by the dashed loop in
the diagram below (the wires in the circuit remain connected for a
complete closed circuit, but this is not explicitly shown on the
diagram for clarity).
The magnitude of the...
