How Do You Make A Magnet Weak?
Electromagnets are magnets that can be turned on and off. Regular magnets lack this quality. The strength of an electromagnet is also easily controlled by altering a few of its properties. It is very possible to weaken the strength of a homebuilt or commercial electromagnet. This is a project better left in the hands of adults, but children can observe. Let’s get started on the adventure. Reduce or limit the current through the coils of the magnet. The strength of the magnetic field is related to the current flowing through the wire wound around the core of the magnet. If the current flow is reduced or limited, the strength of the magnet decreases. A cheap and easy component for limiting current is a simple resistor for homemade electromagnets.. Reduce the number of coils. Another factor in the strength of an electromagnet is the number of coils of wire wound around the core of the magnet. The greater the number of coils, the greater the strength of the magnetic field. Try removing tur
