Magnetism is a force of nature produced by moving electric charges. Sometimes these motions are microscopic and inside of a material known as magnets. Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged ...

Gravitational force and magnetic force, also known as electromagnetic force, are two of the four fundamental forces in the universe. The other two forces are weak interaction and strong interaction, both of which occur in the nucleus of an atom....

The law of conservation of energy tells us that energy can neither be created nor destroyed; it can only be converted from one form to another. These separate forms of energy are not conserved, but the total amount of energy is conserved. If you drop a baseball from your roof, the ball...
Give four properties of electric lines of force. Or. Give important properties of electric lines of forces. View Solution The magnetic lines of force due to the bar magnet View Solution The magnetic lines of force inside a bar magnet : View Solution The magnetic lines of force inside ...
A magnet will only affect ferromagnetic metals, but they also have a faint effect on paramagnetic ones. When you place them near a magnet, the diamagnetic metals express a weak repulsion force. In essence, only ferromagnetic metals have magnetic properties. ...
Magnetic Force Produced by an Electric Current The result of a magnetic field of the conductor is that it will force the magnetic field above the conductor and waken it below. The field lines are like stretched rubber bands; hence they will push the conductor in a downward direction, i.e....
Ferrite Magnets possess strong magnetic fields just like other electromagnets, however, they do not require an electrical force to produce an attraction. They can do that on their own. Since ferrite magnets are not as strong as neodymium magnets, we advise that you do not cut them or alter ...
It takes advantage of two unique properties of high-temperature superconductors: the "Meissner effect" which allows a superconductor to completely repel the magnetic fields around it to achieve levitation, and "flux pinning," which keeps the superconductor steady above its ma...
