How is an electromagnet made from a solenoid? Explain. Write down the differences between bar magnet and electromagnet
Answers
Answer:
electromagnet is made from the solenoid by just rounding the solenoid over a soft iron over it is a temporary strong magnet please shows a magnetic property only when the current passes through the solenoid it get easily demagnetize when we stop the the current. (bar magnet is generally a permanent magnet whose poles cannot be changed and strength between fixed . but an electromagnet the type of magnet whose strength can be changed poles can be changed by just changing the magnitude of current in the direction of current. (((hope this may help you please mark brainliest answer ))))/#@
Answer:
A solenoid consists of many copper wires wrapped together.When electricity is passed through a solenoid it creates a magnetic field and if we keep a soft iron ore between the copper wire it gets magnetised....This is electromagnet
