Hans Oersted, a Dane, was the first to observe the magnetic effect of a current carrying conductor - about 1819.
A temporary magnet.
Natural magnets, like lodestone, are rocks that possess magnetic properties. These magnets occur naturally in the Earth and have a magnetic field. Artificial magnets are man-made magnets created from materials like iron, nickel, and cobalt by aligning their magnetic domains. These types of magnets are used in various everyday applications, such as in electric motors and refrigerators.
It depends on the material the key is made of. If the key is made of a ferromagnetic material, such as iron, then yes, a magnet will attract it. If the key is made of a non-magnetic material, such as aluminum or brass, then the magnet will not attract it.
The most commonly used magnet is made of neodymium, iron, and boron (NdFeB). This type of magnet is known for its strong magnetic properties and wide range of applications.
If the magnet does not pick up any of the nails in the drawer, it could be due to a weak magnetic field of the magnet or the nails being made of a material that is not attracted to the magnet, such as stainless steel. Some nails are made from non-magnetic materials, so they wouldn't be attracted to a magnet.
Magnets first occurred naturally, so "before Man" would be your answer.
A magnet produced in earth; not man made.
no
The strongest man-made magnet in the world is the 45 tesla hybrid magnet at the National High Magnetic Field Laboratory in Florida, USA. It combines a resistive magnet with a superconducting magnet to achieve its record-breaking magnetic field strength.
A magnet is a man-made object, made from minerals that are magnetic or iron that has been magnetized.
the first man was made from God
Yes, cobalt is a magnetic material and will be attracted to a magnet. This is because cobalt has unpaired electrons that align in the presence of a magnetic field, causing it to be attracted to the magnet.
Michael Faraday
there is no magnet but there is a wheel
There's no such thing as a "first magnet". Natural magnets have been around since essentially the big bang.
no it can not .it is because a magnetic meterial can made in to magnet
Magnets exist in nature as natural minerals such as magnetite. However, magnets can also be man-made through processes like magnetization of materials or creating electromagnets.
