Aloop of wire is perpendicular to a magnetic field such that the field is coming straight at you through the loop. the field begins to decrease in magnitude. which direction will the induced magnetic field be (toward/away from you) and which direction will the induced current in the wire be (clockwise/counter clockwise)? explain.

we will have induced magnetic field towards us

now in order to induce the magnetic field towards us we must have induced current in the loop and its direction is counterclockwise.

Explanation:

As per lenz law we know that the rate of change in magnetic flux linked with the closed loop will induced EMF in the loop and the direction of this induced current in the loop will always oppose the causes due to which it is induced

Here we know that magnetic field is straight towards us and it start decreasing with time

So we can say that flux linked with the coil will also decrease with time

Now as per lenz law the induced magnetic field of the loop is in such a direction that it will increase the magnetic flux in the coil.

So we will have induced magnetic field towards us

now in order to induce the magnetic field towards us we must have induced current in the loop and its direction is counterclockwise.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
