Question

Which magnet will you choose among parmant magnet and electromagnet for industrial purpose? justify your answer

Answer 1

Answer:electromagnet

Step-by-step explanation:

i would chose electromagnet for industrial purpose because

• we can adjust the strength of electromagnet by increasing current, no of turns in coil,etc. which cannot be done in case of a permanent magnet because its strength cannot be increased or decreased.
• when you do not need the magnet you can make it lose its magnetic field by simply turning off the current passing through it whereas a permanent magnet will continue to attract metal objects even when there is no need.
