Both are magnetic.
An electromagnet can be turned on and off by controlling the electric current, giving it more versatility in applications. Additionally, the magnetic strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it.
see if a magnet will stick to it someone who knows stuff about magnets please improve this answer. I myself do not know because a magnet will not stick to a very weak magnet but it is still magnetic. EDIT why would you answer if you don't know the answer? You stroke a bar magnet on the material and after a while it either becomes magnetic or not. unless its already magnetic which you would know straight away because it would stick to the bar magnet. sorry if any of my answer doesnt make much sense ... hope i helped someone
Move towards the U magnet so that the poles attach.
Six. Every bar magnet has 2 poles. If a bar magnet is broken, each resultant piece will be a bar magnet in its own right.
A permanent magnet is always on; there isn't any way to turn it off. An electromagnet can be controlled; you can turn it on or off, or change the amount of magnetism by varying the current passing through the coils.
a electromagnet is bigger than a bar magnet
Electromagnets and bar magnets both produce magnetic fields. They can attract or repel other magnetic materials, and the strength of their magnetic field depends on the strength of the current flowing through the electromagnet or the material of the bar magnet. Additionally, both electromagnets and bar magnets can be used in a wide range of applications, from speakers and motors to magnetic levitation systems.
An electromagnet can be turned on and off.
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
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.
It will pick up the nails the same way a bar magnet would do!
bar
The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?
Both a bar magnet and an electromagnet produce a magnetic field. However, while a bar magnet's magnetic field is inherent to the material, an electromagnet's magnetic field is generated by passing an electric current through a coil of wire. Both can attract or repel other magnetic objects based on the alignment of their poles.
The electromagnet can be turned on and off depending on whether it's needed or not.
The magnetic domains in a refrigerator magnet are laid down in parallel strips. They are also re-curved back on themselves so that the back side of the magnet has both north and south poles. If you put two refrigerator magnets back-to-back and move them around a little, it won't take long for you to "feel" the strips of magnetism. The common bar magnet have two simple poles at the ends.
Put the South pole of the nail against the bar magnet to see if it attracts or repels.
