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 into 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. What is Michael Faraday

Explanation / Answer

6) Wire will exert force on each other

As current is flowing in same direction so wire will attract each other

and magnetic field due to them will be different at different points

First option is correct

7) As flux is changing so current will induce

here flux into the page is increasing so loop will generate magnetic field out of the page to oppose it

and using right hand rule we can see that induce current will be counterclockwise

Option A is correct

8) Option A and D is correct
