1. Two powerful magnets are attracted together and heated to about 200 degrees Celsius. At this temperature, the magnetism of magnets is greatly weakened, and the attraction between magnets will be greatly reduced. Two powerful magnets that attract each other will separate. It should be noted that the maximum working temperature of a powerful magnet is 300 degrees Celsius and cannot be heated above 300 degrees Celsius.

2. Put two magnets into an electromagnetic coil and separate the strong magnets by using the principle of demagnetization.

3. Twist the contact surface forcibly to make the contact area smaller or even insert other thin metal sheets for final separation.

4. Use one end of two wooden boards with the same size to pass through a shaft, dig a hole with the same shape as the magnet not far from the shaft, put the attracted magnet into the hole so that the attraction surface is the same as the combination surface of the two wooden boards, and stagger the magnets with the help of the power of the lever.
