Question

As shown in the figure for this question, a conducting wire loop is placed in a magnetic field that is directed perpendicular to the plane of the loop, into the page.

Is the following statement true or false?

Rotating the wire loop about the vertical axis 2 will result in an induced current in the wire loop.

As shown in the figure for this question, a metal bar slides to the right on conducting rails. The setup is placed in an external magnetic field whose direction is unknown. When the metal bar slides to the right, it is found that the induced current in the conducting rails flows counterclockwise. From such information, what is the direction of the external magnetic field?

As shown in the figure for this question, a conducting wire loop is placed in a magnetic field that is directed perpendicular to the plane of the loop, into the page. Is the following statement true or false?

Explanation / Answer

Question 4

True

EMF will be induced becuse if we rotate the area through which magnetic field lines are passing will change

flux is changed so emf will be induced

Question 5

since the force is right ward direction

the direction of field is OUT of the page
