rotor core and shaft.
An electromagnet is a magnet carrying an electric current. This can be useful for many things. eg, door bells.
hit it with a hammer, stroke it with a magnet or flow an electric current through or closely around it!
what are the things pass through magnet fields?
pennies attract magnet
the difference between them are technology is to do with computers and electric things while science is to do with experiments.
battery and a magnet because the ions in a magnet have to be in order for it to be a magnet
The electric bulletin boards are found in those things between routes and towns.
The size of an electric force depends on the amount of charge on the objects involved and the distance between them. The force increases with the magnitude of the charges and decreases as the distance between the charges increases.
Magnetic force is the force between magnets or moving charges, while electric force is the force between electric charges. Magnetic force acts on moving charges perpendicular to both the velocity of the charge and the magnetic field, while electric force acts along the line connecting the charges.
Another use for a magnet is in magnetic resonance imaging (MRI) machines, where powerful magnets create a magnetic field to generate detailed images of the inside of the human body. This technology is commonly used for medical diagnosis and research purposes.
On the gray side of the magnet, if you take out a magnet and put it next to a magnet things you put on the fridge, It sticks to it! You see, the magnet's force is invisible so u can't see it. Or if you put it next to a magnet that sticks to that magnet, You might feel it's force or not. I tried it once :).
