A man from this country spotted a compass needle move when a current was switched on near it he realized that electricity and magnetism were connected?

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 does a current carrying coil with an iron core make?
A choke, an electromagnet, an electric motor stator, an electric motor rotor, etc. all depending on details of construction and use that are unstated in the question.
Is a electromagnet only charged when electric current passes through?
Basically, yes. However, especially when the electromagnet uses iron, it will most likely have some residual magnetism when the current is switched off. Note: You shouldn't used the word "charged" in this context. That refers to electrical charges, and is not usually used for magnetism.
Why my hot water doesn't work but cold water does?
There are a few possibilities why. Troubleshoot asking yourself these questions: Is the hot water heater switched on electronically? Is the stop cock switched on? Are there air locks in the line? Is the hot water heater connected?
What type of material is used for making temporary magnet?
An electo-magnet has an iron core wrapped round with wire coils. When electricity is passed through the coils, the iron core become magnetised, until the electricity is switched off.
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.
How did Oersted discover the relationship between an electricity and magnetism?
He used an electric current to affect the needle of a compass.
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.
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.
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
Is professor snape is a deatheater?
Professor Snape was once a death eater. Once he realized Lily was in danger he switched sides.
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.
What item that continues to use electricity even though its switch may be in the off position?
If a device is switched off at the wall, then that is equivalent of being unplugged and it will not use electricity. However any device with a transformer in it that is switched off at the device (not the wall) will continue to use electricity. Televisions etc are like this, so are mobile phone chargers.
Do UK plug sockets use electric when they are turned on?
they only use electricity when an appliance is plugged in and switched on
What is the cause frequent swithcing of electricity in rainy season?
The electricity is usually switched off during the rainy session because of the winds that usually accompany the heavy rainfall.
What does a current carrying coil with an iron core make?
A choke, an electromagnet, an electric motor stator, an electric motor rotor, etc. all depending on details of construction and use that are unstated in the question.
