Electric charges and bar magnets have the same properties in all aspects. ______

Question

Electric charges and bar magnets have the same properties in all aspects. ________ True or ______ False. For a bar magnet, the magnetic field lines originate from the south to north the pole. ________ True or ______ False. Faraday's Law of Induction defines emf as the time rate of charge of electric flux. ________ True or ______ False. Ampere's Law for a long wire states that magnetic field is directly proportional to current and inversely proportional to the square of distance for the wire. ________ True or ______ False. Ohm's Law is true regardless of the nature of the electric circuit. ________ True or ______ False Ampere's Law for a long wire states that magnetic field is directly proportional to current and inversely proportional to the distance for the wire ________ True or ______ False Two wires carry the same current in the different direction attract each other. ________ True or ______ False Coulomb's Law defines electric force between two charges and the distance between them. ________ True or ______ False. One of the conditions for resonance in an RLC circuit is the impedance should equal to resistance. ________ True or ______ False. The ration of electric field and magnetic field defines the speed of light ________ True or ______ False.

Explanation / Answer

ans1-false

The electric field of a point charge is radially outward from a positive charge whereas in bar magnet is is from north pole to south pole (contradiction between properties)

ans2-false

explanation:

By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet.

ans3-true

Faraday's law states that the EMF is also given by the rate of change of the magnetic flux.

ans4-true
