Question

Two parallel wires each carry current I in the directions as shown. Which of the following is a true statement? A) The two wires are attracted to each other B) The two wires are unaffected by each other C) The magnetic fields generated by the currents cancel everywhere surrounding the two wires. D) The two wires repel each other E) The net magnetic field due to the two wires is uniform everywhere. A conducting loop is formed by running a wire completely around the edge of this page. A uniform magnetic field directed out of the page is increasing at the rate of 2.5 T/s What is the direction of the current induced in the loop? A) The induced current will move counterclockwise around the edge of the page B) The induced current will alternate between clockwise and counterclockwise. C) The induced current will move clockwise around the edge of the page. D)No current will be induced because the loop and field do not have the right orientation. That is James Clark Maxwell noted for? A) He unified the fields of electricity and magnetism into the single field of electromagnetism. B) Rewriting Ampere's Law to include a displacement current. C) He wrote the role for determining the direction of an induced emf, in a conducting loop in a changing magnetic flux. D) His formula for calculating the strength of an induced emf. F.) He discovered that a current through a wire will cause the needle of a nearby compass to deflect.

Explanation / Answer

6.D

The wires repel each other. Field due to lower wire is out of plane. And force on upper wire is upward, so repelled.

7.c

The current induced in such a direction that the induced electrically field opposes the increasing field.

8.A,

Note that option B ,the displacement current is as a result of option A. So Bad can't be called a wrong answer.
