• The basic principle of Physics states that as an electric current flows through a conductor, a magnetic field is generated around the conductor.
• This magnetic field can then exert an influence on the magnetic material in the field.
• The magnetic field causes the magnetic associated with magnets. Electromagnetism comes from the fact that magnetic and electric forces are involved. Electromagnetism is a science that deals with the observations related to electricity and magnetism.  OR
• Electromagnetism is a branch of physics involving the study of electromagnetic force, a type of physical interaction that occurs between electrically charged particles. The electromagnetic force is carried by electromagnetic force is carried by electromagnetic fields composed of electric fields, and magnetic fields, and is responsible for electromagnetic radiation Buch as light Electromagnetic phenomena are defined in terms of electromagnetic force, Sometimes called the Lorentz force.
• Explain by describing an experiment that an electric current in a conductor produces a magnetic field around it.
• Describe that a force acts on a current -carrying conductor placed in a magnetic field as long as the conductor is not parallel to the magnetic field.
• State that a current-carrying coil in a magnetic field experiences a torque.
• Relate the turning effect on a coil to the action of a D.C. motor.
• Describe an experiment to show that a changing magnetic field can induce e.m.f. in a circuit.
• List factors affecting the magnitude of an induced e.m.f.
• Explain that the direction of an induced e.m.f opposes the change causing it and relate this phenomenon to conservation of energy.
• Describe a simple form of A.C. generator.
• Describe mutual induction and state its units.
• Describe the purpose of transformers in A.C. circuits.
• Electromagnetism is the study of magnetic effects of current. The use of electromagnetism in different fields of science and technology is very wide. Motors and electric meters are based on the effect of magnetism produced by the electric current in wires. Generators produce electric current due to the movement of wires near very large magnets.
• MAGNETIC EFFECTS OF A STEADY CURRENT: Ampere discovered that when a current passes through a conductor, it produces magnetic field around it. To demonstrate this, we take a straight conductor wire and pass it vertically through a cardboard. Now connect the two ends of the conductor wire with the terminals of the battery so that current flows through the circuit in the clockwise direction. The lines of force of the magnetic field produced around the wire would be in the form of concentric circles. If we place a compass needle at different points in the region of magnetic field, it will align along the direction of magnetic field. Also if we sprinkle some iron filings on the cardboard around the wire, they will align themselves in concentric circles in the clockwise direction.
• Direction of magnetic field: The direction of the magnetic field is governed by the direction of the current flowing through the conductor. A simple method of finding the direction of magnetic field around the conductor is the Right Hand Grip Rule.
• "Grasp a wire with your right hand such that your thumb is pointed in the direction of current. Then curling fingers of your hand will point in the direction of the magnetic field".
• Magnetic field of a solenoid: A coil of wire consisting of many loops is called a solenoid. The field from each loop in a solenoid adds to the fields of the other loops and creates greater total field strength. Electric current in the solenoid of wire produces magnetic field which is similar to the magnetic field of a permanent bar magnet.
