This 3D magnetic field demostrator is mainly used to teach the physical magnetic field in the middle schhool. It can vividly demonstrate the formation of the magnetic field direction, magnetic induction line direction and magnetic induction line around the magnetic field. This instrument consists of the permanent magnet and the magnetic field lines .

This Portable Hand Crank Generator can be utilized with almost any experiment requiring up to 12-volt DC current, and functions by way of a hand-crank. It is housed in tough clear plastic, allowing the user to view the unit's mechanisms in real-time. This unit is not only functional but also costs about half the price of similar models. This generator can also be used as a hand generated flashlight due to the mounted lamp on the end and the binding post can be used to connect an outside electrical circuit. A great introduction to the concept of motors and generators; makes an excellent gift or addition to the classroom.
