If the cuase for an induced current in a loop is
a decrease in magnetic field, then the direction of
the induced current will be in such a way as to (1 point)


decrease the magnetic field


increase the magnetic field


eliminate the magnetic field


None of the other choices are correct.


All of the other choices are correct.




According to Lenz's Law, the direction of the induced current in a loop is such that it opposes the change in the magnetic flux that caused it. This means that if the magnetic field through a loop is decreasing, the induced current will create its own magnetic field to oppose this decrease.

Thus, the correct statement is:
**increase the magnetic field**

**Tip:** When working with electromagnetic induction, always remember that the induced current creates a magnetic field that opposes the change in the original magnetic field. This opposition is the key concept behind Lenz's Law.
