Electromagnet is the magnet which is becoming active so long current through the coil flows. If current stops then the magnetism disappears. If a core made up of soft iron is used then magnetism will become more intense but the magnetism exists so long the current flows. Any way electromagnet will behave just like a permanent bar magnet. So electromagnet would set itself along the earth's magnetic meridian.

How would you use a electromagnet to move a slide latch in a lock?
To use an electromagnet to move a slide latch in a lock, you would first attach the electromagnet to a mechanism that can physically engage the latch. When the electromagnet is activated by applying an electric current, it generates a magnetic field that attracts a ferromagnetic armature or plate linked to the latch. This action would pull the latch away from its locked position, allowing the lock to open. Once the current is turned off, a spring mechanism could return the latch to its original position, securing the lock again.
What can a electromagnet not move?
An electromagnet is not able to move objects made of non-magnetic materials, such as plastic or wood. Additionally, if the object is too heavy or the magnet is not powerful enough, it may not be able to move the object.
Can an electric current move through a electromagnet?
Yes, an electric current can move through an electromagnet. When electricity flows through the coil of wire in an electromagnet, a magnetic field is created. This magnetic field can then influence nearby objects or align with other magnetic fields.
What are the arrangement of moving magnets and wire coil called?
electromagnet
Why does a compass move when it gets near an electromagnet?
When a compass gets near an electromagnet, the magnetic field produced by the electromagnet interferes with the Earth's magnetic field, causing the compass needle to align with the electromagnet's field instead. This phenomenon is known as magnetic deflection.
A stereo speakers uses an electromagnet to move the cone?
True .
Why does an compass needle move when it is brought near an electromagnet?
A compass needle is a tiny magnet that aligns with the magnetic field around it. When brought near an electromagnet, the magnetic field produced by the electromagnet affects the compass needle, causing it to align with the new magnetic field created by the electromagnet.
What types of metal can a electromagnet move?
only ferrous metals for example, iron.
What type of magnet would you use to move around old cars at a junk yard?
A electromagnet is often used to lift up junk cars.
How do you make a remote to electromagnet?
To make a remote-controlled electromagnet, you would need a remote control system, an electromagnet, and a power source. You can connect the power source to the electromagnet through a relay controlled by the remote system, allowing you to turn the electromagnet on and off wirelessly. This setup would enable you to control the magnetic force remotely.
What are the advantages of Permanent magnet over Electromagnet?
Unlike a permanent magnet, an electromagnet can be turned on and off. One useful advantage of this: Place a metal bar inside the electromagnet, apply current through the electromagnet in one direction, and the magnetic field would move that bar one way -- reverse the current reverses the magnetic field and the bar would move the opposite way. You could use that effect and make an electronically controlled lock for a door.
What is the purpose for an electromagnet in a simple doorbell?
to produce magnetic field to move the piston of the doorbell
