The current I in the long straight wire illustrated above is

The current I in the long straight wire illustrated above is increasing in time with the relation I=4f A. What is the direction of the induced current in the rectangular loop and the force between the loop and the wire, respectively? Neglect gravity in this problem. clockwise, attractive counterclockwise, attractive counterclockwise, repulsive There is no induced current in the loop and therefore there is no magnetic force, clockwise, repulsive

Solution

clock wies

as current is increasing with time positively in the wire

which mean, magnectic field above the page will increase in the loop due to wire ....so induced current will flow in cloack wise direction to oppose the magnetic field

=> it will be replusive too
