What is the term for producing a current by changing a magnetic field?
2 answers:
<u>Explanation </u>:
When a coil is placed in changing magnetic field then a current will induced in the coil. The current caused due to changing magnetic field is called as induced current.
Due to changing magnetic field an emf is induced in the coil. Emf is defined as the rate of change of magnetic flux in the coil
This emf then causes induced current in the coil. It is given by :
Hence, by changing a magnetic field an emf is induced which in turn causes induced current.

Data:
The charge of a body depends on the amount of electrons it gains or loses. Q = n * e, where "Q" is charge, "n" is the number of plus or minus electrons, and "e" is the fundamental charge of an electron
<span>. To know if the body has gained or lost, we look at the signal of its charge, remembering that the electron is negative. The charge of the body is 4 μC (positive), so there is a lack of electrons!
Q = 4 </span>μC →

Answer:
Ohms law states that current is directly proportional to the potential difference across the ends of a conductor provided that temperature and other factors kept constant
