In the factories, Electromagnet is used to remove scrap iron from the waste. Electromagnet is fitted to a crane. When the operator switches it on by the electricity scrap iron is attracted towards the Electromagnet.
a piece of soft iron is taken, and then a insulated copper wire is spun around the piece of soft iron about 100 times. now a battery is connected to the copper wire.the copper wire works with the help of a dry cell(DC).
Basically in physics a magnet electrically charged posses a energy form called electromagnetic energy. This one posses a hole and a particle when made. Obviously particle will go in the hole and this is why electricity is defined as flow of electrons. Electromagnet is a temporally charged one used in MRI's, robots, etc.
An eukaryotic cell is a cell which is properly developed and well developed nucleus.It has a membrane around it called the nuclear membrane which separates it from the cytoplasm of the cell.The DNA is present in the nucleus.In case of prokaryotic cell there is scattered nuclear region called nucleoid region lacking a nuclear membrane.
North-North or South-South directions repel but why the magnets attract towards the earth's North Pole?
