Question

Two electromagnets contain the same types of magnets

and wires. But the magnet In the first moves much faster
than the second. Therefore:
The first electromagnet has a more powerful current than
the second
The first electromagnet has a less powerful current than
the second
The currents in the two electromagnets run in opposite
directions
The current in the first electromagnet moves faster than
the current in the second electromagnet

Answer 1

Answer: The first electromagnet has a more powerful current than

the second

Step-by-step explanation:

Since the two electromagnets contain the same types of magnets and wires. If the magnet In the first moves much faster than the second. Therefore:

The first electromagnet has a more powerful current than the second

Because the induced EMF is proportional to the induced current.

Where the induced EMF depends on the speed of the magnet according to the formula below

EMF = BVL

So, increase in speed of the magnet will cause more powerful induced current and emf
