Which one of the following is true? The emf induced in a circuit is.. Select one: The magnetic field strength at a distance of 0.5 cm from a very long straight current carrying wire is a. directly proportional to magnetic flux through the loop of the circuit found to be X. What is the magnetic field strength at a distance of 2 cm from the wire? directly proportional to the time rate of change of the magnetic flux through the loop of the Select one:& circuit O a 2x O c. always positive O b. still x O d. inversely proportional to the time rate of change of the current in the loop of the circuit Oc wx Od 4x The inductance of a uniformly wound solenoid of a given length, number of turns and cross sectional area. Select one: 2 A charged particle moving at a constant velocity enters a uniform magnetic field. If the particle does O a. depends on the current through the coil not interact with anything other than the magnetic field, which of the following, if any could be O b. depends on the time rate of change of the current through the coil different when the particle leaves the magnetic field? -. O c. depends on both of the above Select one: O d. is constant 5 O a. the velocity of the particle O b. the particle's speed An inductor is similar to a capacitor in that - O c. the particle's kinetic energy 3 Select one: O d. none of the above O a. Both can store energy in electrical circuits O b. In the clise of an inductor, the energy stored is proportional to the current squared and in the case of a capacitor, the energy stored is proportional to the charge squared. O c. The energy in an inductor is stored in its magnetic field and the energy in a capacitor is stored in its electric field O d. All of the above Please help me answer these questions (1 to 5) with clear explanations. Thanks
