What is an eletro magnetic?
Electro magnets are only magnetic when an electric current is flowing, unlike a standard magnet which is always magnetic. When the electric current is switched off, the magnetism decays away (collapses). They normally take the form of a fixed core made of soft iron surrounded by a coil of copper wire which acts as the conductor for the electric current. There is a special form of electro magnet which has a movable core instead of it being fixed and this type of electro magnet is called a solenoid. You can see large electro magnets at work at a scrap metal yard, where they are employed on a crane jib to lift and transport scrap iron and steel.
How do you in install magnet on crank?
To install a magnet on a crank, you can use an adhesive or epoxy to secure the magnet to the crank arm. Make sure the surface is clean and dry before attaching the magnet. Ensure that the magnet is positioned correctly to align with the sensor for accurate readings.
What will a magnet pick up?
a magnet will pick up another magnet. magnet will stick to iron. Fun Activity: if you have more than one magnet you can play a trick to your friends. you just need one magnet under a iron desk and put another magnet over on top of the desk. once you did that make sure that your friends doesnt see your hand under the desk and touching the magnet. slowly move the magnet under the desk so that it doesnt make lots of noise. then once you move the magnet under the desk the other magnet that is on top of it on the desk will move.
What type of magnet can only attract materials when it is touching another magnet?
A temporary magnet, such as an electromagnet, can only attract materials when in contact with another magnet or when an electric current is flowing through it. It loses its magnetism when the current is turned off or the magnetic field is removed.
Do they make an all negative magnet?
No, it is not possible to create an all-negative magnet because magnets have two poles - north and south. The concept of an all-negative magnet conflicts with the fundamental properties that define magnets.
What is a way to make a very powerful electro magnet?
Put a magnet into AC electricity
How do you do a needle?
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
What materials do you use to make an electro-magnet?
an iron nail, a long peice of wire, a large battery or a transformer
Why are hard magnetic materials used to make electromagnets?
Hard in this sense means materials that are themselves not easily magnetised. In fact, the part that you are referring to isn't really the magnet - it is the core, the magnetic field is produced by the coil, the core just concentrates the field. In an electro-magnet, the core must retain little or no field when the coils are not excited/energised. This means that items picked-up/attracted by the electro-magnet are no longer attracted when the coil is denergised - you can unload/drop the load from your crane or hoist by switching off the electro-magnet.
How do you make an electro magnate?
Can we make ordinary to an electro..... how can we make it....
How do you get the spring on clockwork repairs on club penguin?
You go to the ice-berg and it will be floating there. You need to get the electro magnet from G and bring it there and the electro magnet will attract the spring. THen you go to the gadget room and put it in the test chamber. Press the fire button. The ice around the spring will melt, and then finish the mission.
What are the benefits of using an electromagnet rather than a bar manet?
An electro-magnet can be switched on & off - a bar magnet is 'permanent' Think of a scrap-yard. If the magnet they use to pick up huge quantities of metal were permanent, they'd have to manually remove every piece. With an electro-magnet, they simply turn the power on to pick up a load, and off when they want to release it. You can make your own electro-magnet with a battery, some wire and a large nail.
What could you do to an electro magnet to make it weaker?
You can pull the cord from the magnet to make it weaker so it wont pick up as many items you think it will
Can you magnitize alumininum nails?
Not at room temperature, however you can make it into an electro-magnet by passing a current through it. If you cool Aluminium down to 1.2 Kelvins then it becomes a superconductor and will behave as if it's magnetic.
How does venom beat electro in ultimate Spider-Man ps2?
He will catch electro and make him into symbion electro and venom will do anything he want
How do you magnetise a needle?
You can magnetize a needle by rubbing it against a magnet in one direction multiple times. This process aligns the magnetic domains within the needle to create a magnetic field. Alternatively, you can use a strong electrical current to induce magnetization in the needle.
Does a electromagnet work without a battery?
Electro Magnets can work without battery power, hook up a really powerful solar panel and a resister to circulate an even current, add strands of copper wire and coil them around a tube to make them circular. hook them up to the solar panels to make the electro magnet's power circulate through the wire!! I tried it and its fun!
