Nolan set up the equipment shown in order to induce a current in a wire. which best explains why no current is induced?

(a)the wire needs to be coiled less tightly.

(b)the wire needs to be straight, not coiled.

(c)the magnet needs to be moved through the coils of wire.

(d)the magnet needs to be held above the coils of wire.

(C)The magnet needs to be moved through the coils of wire.

Explanation:

As we know that rate of change in magnetic flux linked with a closed loop will induce the EMF in the closed loop

so it is given as

here we know that

now here in order to change the flux we need to change the magnetic field linked with the closed loop

so here when we move the magnet then the magnetic field of the magnet linked with the coil will also change and that will induce the current in the coils

So correct answer is

(C)The magnet needs to be moved through the coils of wire.

d is the answer i came up with

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
