Many metals cannot be picked up by electromagnets (at room temperature). For instance, aluminum, gold, Mercury, and copper will not be attracted to an electromagnet.
Iron sticks to an electromagnet at normal temperatures. If iron is too hot, it loses its magnetic abilities. This is true of all metals: if they're cold enough they exhibit magnetic properties, if they're too hot they don't show magnetic properties. Even mercury (liquid at room temperature) can be made magnetic if it's cooled to very low temperatures.

How were magnets used in junk shop?
since magnet can be used to pick up objects of metal especially electromagnets because their power can be increased and descreased . The load can be left and picked by passing electricity and stopping it
What Sediments can be picked by?
Sediments can be picked up by wind, and water.
How magnets and electromagnets make a can sorter work?
Magnets will pick up steel cans, lifting them away from a solid waste stream. Additionally, rapidly changing magnetic fields can be used to "pop" other metals out of a solid waste stream, through current induced in those metals.
What three ways are magnets and electromagnets alike?
Both magnets and electromagnets have a magnetic field that can attract or repel objects. They can both be used to pick up and manipulate metal objects. Both magnets and electromagnets rely on the alignment of the magnetic domains in their material to generate a magnetic force.
Solenoids are made up of what type of magnet?
Solenoids are made up of electromagnets. These electromagnets consist of a coil of wire that generates a magnetic field when current passes through it. This magnetic field can be used to move a plunger or armature within the solenoid.
Why are electromagnets used for picking up heavy metals?
Well electromagnets have great power so it is understandable that someone would use it to pick up heavy metals.
What metals can electromagnets pick up for example stell etc.?
Iron, Cobalt and Nickel.
Why are electromagnets used in metal scrap yards?
Electromagnets are used in metal scrap yards because they can easily pick up and sort large quantities of ferrous metals from non-ferrous metals. By using an electric current to create a magnetic field, electromagnets attract and collect ferrous metals such as iron and steel, allowing for efficient separation and processing of different types of metals.
Why do electromagnets pick up metals?
Electromagnets pick up metals because when a current flows through the wire coils, it creates a magnetic field. This magnetic field attracts metallic objects, such as iron or steel, towards the electromagnet. The magnetic force overcomes the force of gravity, allowing the electromagnet to pick up metal objects.
Can a two pound coin be picked up by a magnet?
No. Coins are manufactured from non-magnetic metals.
What are the some uses of electromagnets?
Electromagnets are used in scrapyards to pick up and drop metals that are magnetic because electromagnets are temporary which means you can turn it on and off. They are also used in hospitals and opticians to get metal out of your eye or body, You don't use a normal magnet because if you were in the middle of taking something out of someones eye you would need to be able to stop immediately in case you end up causing more damage.
What is an example of a sentence using the word electromagnet?
Electromagnets are widely used now. Instead of traditional magnets.
How were magnets used in junk shop?
since magnet can be used to pick up objects of metal especially electromagnets because their power can be increased and descreased . The load can be left and picked by passing electricity and stopping it
When is your dog too heavy to be picked up by the nape of the neck?
its to heavy when its over 20kg it also to fat if you cant grab skin thereAnother answer:Unlike cats, dogs should NOT be picked up by the nape of the neck at any size.
Why cant you find the first death card in the shack to the right in call of duty world at war?
you have probably already picked it up
Can a magnet pick up platinum gold?
No, platinum and gold are not magnetic, so they cannot be picked up by a magnet. They are both precious metals that have different properties than magnetic materials.
Why does a platypus have to be picked up by its tail?
The platypus should not be picked up by its tail. In fact, it should not be picked up at all.
