State whether following statements are True or False:
(a) An electric motor converts mechanical energy into electrical energy
(b) An electric generator works on principle of electromagnetic induction
(c) The field at the center of a long circular coil carrying current will be parallel straight lines
(d) A wire with a green insulation is usually the live wire of an electric supply
An electric motor converts electrical energy into mechanical energy. As current carrying coil is placed in a magnetic field, it experiences a force due to which it starts rotating.
An electric generator works on the principle of electromagnetic induction. When the coil is rotated by external mechanical forces in a magnetic field, the magnetic flux through the coil changes. This creates an induced emf in the coil and hence induced current flows.
The field at the center of a long solenoid carrying current will be parallel straight lines. This can also be verified by Right hand thumb Rule.
Live wire has red insulation cover, whereas earth wire has green insulation colour in the domestic circuits.
Question 1. Enumerate the properties of a Magnet.
Answer. The properties of a magnet are as follows:
Question 2. Explain the experiment conducted by Oersted.
Answer. In 1820, Hans Oersted conducted an experiment known as the electromagnetic field base. During this experiment, he observed that when electricity passes through a conducting wire, a magnetic field is produced around it. When a compass is brought near the wire carrying the current, the needle of the compass deflects in a definite direction. He thus detected the magnetic field with the help of a compass. The direction of the electromagnetic field is depicted by the direction of the deflected needle. This experiment is also known as the base of the electromagnetic effect.
Question 3. What are the properties of Magnetic field lines?
Answer. The properties of Magnetic Field lines are:
