Question

How does the magnitude of induced current changes in a closed coil when a more powerful magnet is used?

Answer 1

Answer:

the magnitude of indused current changes in a closed coil when a more powerful magnet is used because the powerful magnet attracts the current and creates electromagnetic energy

Answer 2

Answer:

The magnetic strength is directly proportional to the magnitude of electric current ,that is more is the magnitude of current ,more is the strength of magnetic field .

Explanation:

Induced current

• It is the current that is produced when conductor is moved between poles of magnet .
• As we move the conductor between poles of magnet , it cuts the magnetic lines of forces ,due to which magnetic flux changes which further changes the strength of magnetic field .
• Now if the powerful magnet is used , that simply implies the magnetic field produced is quite stronger , so when conductor is moved w.r.t magnet or vice versa , strength of flux is much affected and that is the reason induced current is of high magnitude .
• Direction of induced current can be found by Fleming's right hand rule
