Solution
Verified by Toppr
Permanent Magnets:
1
)
High Retentivity: Magnet should be strong
2
)
High coercivity: Magnetisation should not get affected by stray Magnetic fields
Electromagnets:
1
)
High Permeability core of Iron for easy magnetisation
2
)
Low Retentivity: For easy magnetisation/demagnetisation.
