The country was Denmark - the physicist in question was Hans Christian Oersted.

However the majority of the work in this field was undertaken by British physicist Michael Faraday and continued by James Clerk Maxwell who was Scottish.

What happens to an electromagnet when the electricity supplying it is switched off?

When the electricity supplying an electromagnet is switched off, the magnetic field produced by the electromagnet disappears. This means that the electromagnet loses its magnetic properties and no longer attracts or repels magnetic materials.


What is the time taken for a power station to produce electricity after it is switched on called?

The time taken for a power station to start generating electricity after it is switched on is called the "ramp-up time." This includes the time needed for the turbines to reach their full operational speed and for the electrical systems to stabilize before electricity can be delivered to the grid.


what energy conversion is takes place when a toaster is switched on?

Electrical energy is converted to heat energy when a toaster is switched on. The electricity flows through the heating element, which creates resistance and generates heat to toast the bread.


How did Albert Einstein discover electricity?

History doesn't record the actual event, but it's almost certain that Albert Einstein discovered electricity either the first time he opened his Physics book or the first time he switched on the light in his bedroom as a child. Electricity had been thoroughly investigated by the time Einstein was born.


What does a current carrying coil with an iron core make?

A current carrying coil with an iron core creates an electromagnet. The iron core enhances the magnetic field strength produced by the coil, making it more effective for applications like electric motors, transformers, and solenoids.

How did Oersted discover the relationship between an electricity and magnetism?

Hans Christian Oersted discovered the relationship between electricity and magnetism in 1820 when he observed that an electric current flowing through a wire caused a nearby compass needle to deflect. This observation demonstrated that an electric current produces a magnetic field.


What is the main benefit of a electromagnet?

the main benefit of a electromagnets is that they are small, light ,and use a low amount of electricity All electric motors convert electricity into a magnetic field that turns a rotor. The kinetic energy is instant and the space condensed. Alterative answer: Their magnetism can be switched on and off.


Mrs frisby realized that had had somehow switched their positions?

Mrs. Frisby realized that the rats had somehow switched places with her home - moving it to a new location without her knowledge. She was shocked and confused by this unexpected turn of events.


How will your computer hibernate with out electricity?

A computer is only not using electricity when it's switched off.


How do magnets in a crane work?

They are an electromagnet which is a wire coil wound outside a large iron core. When the coil is energized with electricity by the crane operator it creates magnetism and when the power is switched off the magnetism stops. This type of magnet is what makes a car starter engage, electrical solenoids are a version and many common household items utilize electromagnets. Trunk release on your car, etc.


Do electromagnets lose strength?

Only once the electricity is switched off.


What is the diagram for a switched outlet?

A diagram for a switched outlet shows how an electrical outlet is connected to a switch, allowing the outlet to be turned on and off using the switch.


Why in an electrical lab a bulb connected to supply goes off slowly when the main supply is switched off?

the electrons in the wire connected to the bulb take a while to fade away completely as the main energy source is turned off, causing the bulb to glow faintly until all of the electricity is out of the system

What uses more electricity a lit light bulb or an empty socket of the same rating switched on?

When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
