CBSE Class 10 Physics Magnetic Effects of Electric Current
Magnetic FieldThe space around a magnet in which the force of attraction and repulsion due to the magnet can be detected is called the magnetic field.
The magnetic field lines around a straight conductor carrying current are concentric circles.
The direction of magnetic field is given by Right Hand Thumb Rule.
The magnetic field inside a solenoid is uniform.
Magnetic ForceA current-carrying conductor when placed in a magnetic field experiences a force.
The direction of force is given by Fleming's left-hand rule.
An electric motor is a device that converts electric energy into mechanical energy and it works on the principle of force experienced by a current carrying conductor in a magnetic field.
Electromagnetic InductionThe phenomenon in which an electric current is induced in a circuit because of a changing magnetic field is called electromagnetic induction.
Fleming's right hand rule is used to find the direction of induced current.
Electric generators are based on the principle of electromagnetic induction and converts mechanical energy into electrical energy.
