rectangular loop of wire is pulled out of magnetic field B, at a steady velocity v, and in a direction perpendicular to a field. FIgure 5 Shows that the machine must do work at steady rate of P=(B2I2v2)/R as the loop is exiting the field as shown above Identify if it is easier to pull the loop out of field if the electrical resistance of the wire were increased? Justify your answer. Compare the changes of induces current (if any) in the loop when the loop is entering the magnetic field and leaving the same field. By moving its plane parallel to uniform magnetic field, predict what will occur to the loop of wire. Think and write down a device in your area right now which applies the concept
