Physics : Magnetizer

Description

Devices that can penetrate strong magnetic fields to carbon steel’s dense steel and insert or remove magnetic force
It is magnetized by DC current and can be demagnetized by AC current.
Experimental method
When you want to insert magnetic force, put the sample into the bobbin of the magnetizer and place the switch in the magnetization position and push it 2-3 times at intervals of 0.5 ~ 1 second.
In case of de matching, put the switch in the demagnetizing position, push the push button as in the case of magnetization and take out the object slowly. Power AC 220 V, 2 magnetized balls
