Is there an attraction between magnets and steel?
If the steel is big, magnet-to-steel is the same as magnet-to-magnet. With a large steel surface, the pull force from a magnet to the steel is about the same as the pull force to a second, identical magnet. When you handle a magnet and a piece of steel, it does seem to feel weaker than a magnet to another magnet.
Why is a steel ball attracted to a magnet?
The magnetic force is able to pass through the glass and attract the steel ball bearing on the other side. This is because iron is a magnetic material.
Can a steel ball be magnetized?
You can magnetize a ball bearing or other small, steel object by rubbing the steel along the magnet, instead of vice versa.
Which will be attracted to or repelled by a magnet?
The rule to remember is that opposites attract. Every magnet has both a north and a south pole. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.
Is Gold magnetic?
Gold had long been considered a non-magnetic metal. But researchers recently discovered that gold can in fact be magnetized by applying heat. Gold had long been considered a non-magnetic metal. But researchers at Tohoku University recently discovered that gold can in fact be magnetized by applying heat.
Can magnets work through glass?
Yes, magnetic fields will certainly pass through glass. That attraction indicates that the magnetic field is propagating through the glass. If the magnets are strong enough, the magnets will even attract each other through your own hand!
At which part of the magnet the magnetic attraction is maximum?
The attractive property of a magnet is maximum at north and south poles both.

What does a magnet repel?
A Magnet’s Repelling Force Opposites attract. To explain why magnets repel each other, a north end of a magnetic will be attracted to the south of another magnetic. The north and north ends of two magnets as well as the south and south ends of two magnets will repel one another.
What metals do magnets repel?
Why are all metals magnetic?
| Type of Material | Response to Magnets |
|---|---|
| Superconductor (special materials at low temperatures) | strongly repelled |
| Diamagnetic (all materials) | weakly repelled |
| Paramagnetic (e.g. oxygen, tungsten, aluminum) | weakly attracted |
| Ferromagnetic (e.g. iron, cobalt, nickel) | strongly attracted |
Can the pull force of a magnet be greater than steel?
The Pull Force Calculator screenshot below shows how, for distances greater than zero, the magnet-to-magnet pull force can be greater than the magnet-to-steel. Two magnets (left) pull to center upon one another, while a magnet and a steel disc (right) can stick together offset.
Why do bar magnets stick together and sometimes repel?
Bar magnets only sometimes stick together and sometimes repel because each has a north pole and a south pole. Opposite poles attract, and like poles repel. If you were to put two north poles together, they would repel, but a north and a south would stick together.
What happens when you put a magnet in a magnetic field?
However, the directions of those magnets are all scrambled up, so the total magnetism cancels out. If you put them in a magnetic field, the domains tend to line up with the field, so you get something which really has net magnetism and can feel a force from the field.
How do you test the pull force of a magnet?
We use a thick, solid steel plate that has been machined to be nearly perfectly flat. It is larger than the magnet being tested. A pull force gauge measures the force required to pull the magnet away from the steel plate. If you stick your magnet to an overhead I-beam, you should see results just like our Pull Force Case 1 numbers.
