Bring older, weaker magnets back to life with this magnetizer. A 25cm long coil allows magnets up to 4.5cm in diameter to be either remagnetized or demagnetized.
This coil serves as a useful way to demonstrate how a magnet can be made or destroyed.
Two banana plug jacks allow for an AC/DC power supply to be attached, and an on/off switch is clearly visible.
