the magnetic field of a magnet is measured through Gaussmeters.
the magnet attracts to iron by the magnetic field both the iron and the magnet have
can be separated by using a magnet
It depends on the type of lamp and the strength of the magnet. An incandescent lamp works literally by running current through the filament to heat it. Parts of the bulb might be magnetic, so if the magnet were ridiculously powerful it might deform or break them. Fluorescent and Neon lamps use ionization, so although I haven't tried it, I'd bet a reasonably strong magnet might affect them. If you have an old CRT-based television or computer monitor you can see how this works by placing a magnet near it -- note, this can cause permanent effects to the picture quality, so either keep the magnet at a distance where the effect is minimal or use a CRT you don't care about. LED lamps are so small and well-constructed that I think they're more like incandescent lamps -- a really powerful magnet might damage them, but otherwise is unlikely to affect them.
Lodestone is an example of a natural magnet.
well if a yellow light of deaf from overheating (witch mine did) a magnet can
An electromagnet can raise a barrier by generating a magnetic field when an electric current flows through it. When the magnet is activated, it pulls a metal armature attached to the barrier, lifting it up against the force of gravity. The strength of the electromagnet determines its lifting capacity.
You can control the strength of an electromagnet by adjusting the current flowing through it, which is not possible with a permanent magnet. Additionally, you can turn the electromagnet on and off by controlling the electric current, allowing for greater flexibility in applications such as lifting objects or generating magnetic fields.

An electromagnet would generally be better for lifting heavy metal objects as its magnetic strength can be easily controlled by adjusting the electrical current. A permanent magnet may not have sufficient magnetic strength to lift heavy objects, and it does not offer the flexibility of adjusting its magnetic force.
An electromagnet is a temporary magnet that only produces a magnetic field when an electric current is flowing through it, while a permanent magnet retains its magnetism without needing an external electric current. Additionally, the strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it, while the strength of a permanent magnet is fixed.
A lifting magnet is an electromagnet that is meant to hold or move material that comes in contact with the magnet. This is the opposite of a traction magnet.
electromagnet
The magnet on the surface and the metal 300 ft down - no. Lowering the magnet to the metal, then lifting - yes.
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
No, as in this case,the rod is the magnet,and the strength of a magnet does not depend on its size.
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
