Paragraph on “What is an Electromagnet?” complete paragraph for Class 9, Class 10, Class 11 and Class 12
What is an Electromagnet?
A compass needle will only point north- south if there are no other magnets near it. If there are, the needle will be attracted towards them and will point in a different direction or be deflected. It was discovered that if a compass was held near a wire carrying an electric current, the needle was deflected. But, if the current was switched off the needle swung back and pointed north-south again. This meant that the current was acting like magnet. If some wire is wrapped around a magnet and a current passes through the wire, the magnet will become much stronger. This is known as an electromagnet.
