Specification Brand : Dntum BulletPoint1 : This instrument demonstrates the relationship between the direction of the ampere force and the magnitude of the ampere force and the current intensity, the length of the energized wire, and the intensity of the magnetic line of induction. BulletPoint2 : The wire frame (conductor) is deflected under the action of ampere force in a uniform magnetic field, and the wire frame is affected by the horizontal component of its own gravity. When the two reach a balance, the plane of the wire frame deflects to a certain angle to stand still (The greater the angle, the greater the ampere force received), the deflection angle is magnified and displayed on the dial by the pointer, which greatly improves the visibility of the experiment. BulletPoint3 : Before use, the pointer should be calibrated to point to zero scale. BulletPoint4 : When using, make sure that the three contacts of the wire frame are in good contact with the connecting reeds of the terminal. If necessary, the contact points can be polished with fine sandpaper. If the contacts in the middle are not in contact with the reeds, the reeds can be properly pressed down. BulletPoint5 : When transporting the instrument, avoid collisions and drops to avoid deformation of the wire frame and pointer and the magnetic needle from falling off.

The pointer should be calibrated to make it point to zero scale before use. 2. When using, make sure that the three contacts of the wire frame are in good contact with the connecting reeds of the terminal. If necessary, the contact points can be polished with fine sandpaper. If the contacts in the middle are not in contact with the reeds, the reeds can be pressed down appropriately. 3. When transporting the instrument, avoid collision and falling to avoid deformation of the wire frame and pointer and the magnetic needle from falling off.
