The magnetic field exerts a force on the charged particles in the rod, causing them to align and create a repulsive force between the rod and the magnet. This repulsive force can balance out the force of gravity, resulting in levitation.
You will need a magnet, a rod made of a magnetic material, and a power source to create the magnetic field. The strength of the magnet and the material of the rod will determine the stability and height of the levitation.
No, only materials that are magnetic, such as iron, nickel, or cobalt, are able to be levitated using a magnetic field. Non-magnetic materials, like wood or plastic, will not respond to the magnetic force.
The height of the levitation can be controlled by changing the strength of the magnetic field. This can be done by adjusting the distance between the magnet and the rod, or by changing the power source that creates the magnetic field.
Yes, it is possible to levitate multiple rods using one magnetic field. However, the stability and height of the levitation may be affected by the number and arrangement of the rods. Additionally, the strength of the magnetic field may need to be increased to support the weight of multiple rods.
