iron
Not necessarily; tin is not magnetic, for example.
The atmosphere of the earth is a magnetic filed
Iron
Some examples of dynamic units are magnetic disks, magnetic drums, and magnetic tapes
Magnetic metals
Steel is a magnet material, but not all metals are magnetic, like Aluminum.
One example of a non-magnetic metal is aluminum. It does not have magnetic properties because its atoms do not align in a way that creates a magnetic field.
No, a magnetic force is not an example of lightning. Lightning is a sudden electrostatic discharge that occurs during a thunderstorm, while a magnetic force is a force that acts between magnets and magnetic materials. Lightning involves the movement of electrical charges in the atmosphere, while magnetic forces arise due to the alignment of magnetic dipoles in a material.
The common example is iron.
When I charge my iMac computer it has a magnetic force to it so that I know that it is plugged in.
substances that only become magnetic when something that IS magnetic is put close to them. like your fridge is an example
