Why
are
electromagnet more
stronger
than the parmanent magnet ?
Answers
Answer:
Electromagnets have the main benefit of manipulating their magnetic pull strength – both by turning the magnet on or off and by adjusting the current. They also feature greater pull strength than permanent magnets. Some estimates place the largest electromagnet at 20 times stronger than the strongest permanent magnet.

Answer:
Electromagnet are more stronger than permanent magnet because electric current and magnetic field can be changed as per need. But In permanent magnet we can not change the direction of magnetic field. We can change the polarity of electromagnets but not in permanent magnets. Electromagnets can lift heavy weight also. So that's why electromagnets are more stronger than permanent magnet.
