Metal which has high magnetic power?

Iron is a metal with high magnetic power. It is capable of being magnetized and retains its magnetism well, making it a common material for magnets and magnetic applications.


How do you calculate the power need to carry a particular mass by magnetic levitation?

The power needed to levitate a particular mass using magnetic levitation depends on the strength of the magnetic field, the distance between the magnets and the object, and the speed at which the object is moving. This can be calculated using the formula: Power = Force x Velocity. The force exerted by the magnetic field and the velocity at which the mass is being carried are key factors to consider in this calculation.


What are two advantages of a natural magnet over electromagnet?

One advantage of a natural magnet is that it does not require any external power source to maintain its magnetic properties, unlike an electromagnet that requires electricity to operate. Natural magnets are typically more stable and retain their magnetism for a longer period of time compared to electromagnets that can lose their magnetic properties when the electric current is removed.


What happens when you remove the power source from an electromagnet?

When you remove the power source from an electromagnet, the magnetic field that was being generated by the flow of electric current through the coils of the electromagnet dissipates. As a result, the electromagnet loses its magnetic properties and no longer attracts or repels magnetic materials.


If you circulated copper wire to magnet and pass current through copper wire it then power of magnet is incrase?

When you pass an electric current through a copper wire that is wound around a magnet, it creates a magnetic field that aligns with the magnetic field of the magnet. This process strengthens the overall magnetic field around the magnet, effectively increasing its power. This principle is the basis of how electromagnets work.

Do dynamic microphones require a power source?

No, dynamic microphones do not require a power source to function. They generate electrical signals through electromagnetic induction when sound waves cause a diaphragm to move within a magnetic field.


Does the "Stamina Magnetic 1772 Cross Trainer Elliptical" require an electrical power source for use?

What are magnets that do not require any power of force to maintain their field called?

They are called permanent magnets. These magnets retain their magnetic field without the need for any external power source or force to maintain them.


How much power do electronic door locks require as minimum?

Electronic door systems require a minimum of 1 pound per square inch of power per door lock. If it is a magnetic lock, 10 pounds per square inch is adequate and considered secure.


How can I build a magnetic motor?

Building a magnetic motor involves creating a device that uses magnets to generate motion and produce energy. To build one, you will need a strong magnet, a coil of wire, and a power source. By arranging the magnet and coil in a specific way and supplying power to the coil, you can create a magnetic field that induces motion in the motor. It is important to note that building a magnetic motor can be complex and may require a good understanding of electromagnetism and engineering principles.


What is the formula for calculating power if you are given magnetic field?

The formula for calculating power if you are given a magnetic field is sub 43


The left light on your pintara has stopped working globes OK fuse OK no power to wire at light Help?

If the left light on your Pintara has stopped working, but the globes and fuses are okay, the wire may have a problem which causes it to lose power. To determine the problem, trace the wire to check for a break.


What depend on a magnetic compass?

The navigator and hence the exploration group, who trust navigation to the navigator. A2 Even modern ships have magnetic compasses. They are a fail safe alternative to all the other electronic navigation aids, because they require no power to work.
