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: The first electromagnet has a more powerful current than

    the second

    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
