Chapter-4|Moving Charges and Magnetism| NCERT 12th Physics: Magnetic Force on a Current Carrying Conductor (In a Uniform Magnetic Field): We know that a moving charge particle experiences a magnetic force in a magnetic field and the value of force is F= q(V×B). A current carrying wire has a chargers moving inside it opposite direction of […]

Chapter-4|Moving Charges and Magnetism| NCERT 12th Physics: Cyclotron: It is device used to accelerate charged particle like proton and alpha-particle etc. to very high energies. It was invented by E.O. Lawrence and M.S Livingston in 1934. Principle: A charged particle can be accelerated to very high energy by making it pass through a moderate electric

Chapter-4|Moving Charges and Magnetism| NCERT 12th Physics: Force on a Moving Charge in a Uniform Magnetic and Electric Field (Lorentz Force):   When we combine these two forces then we find Lorentz Force, If we adjust the value of E and B such that magnitude of two forces are equal and opposite in direction then

Chapter-4|Moving Charges and Magnetism| NCERT 12th Physics: Motion(Path) of Charged Particle in Magnetic Field: We know that in circular motion moving object motion will be balance by centripetal force. Some Important Concept:

Chapter-4|Moving Charges and Magnetism| NCERT 12th Physics: Force on a Moving Charge in a Uniform Magnetic Field:   There is no Force Act on Charged Particle:   Direction of Magnetic Force: By following method we can find the direction of magnetic force.   Note: (I) Firstly put your thumb, fore finger and middle finger perpendicular

Chapter-4|Moving Charges and Magnetism| NCERT 12th Physics: Toriod: The toroid is a hollow circular ring on which a large number of insulated turns of a metallic wire are closely wound. Toroid is used in devices such as synchrotron in which high magnetic field is required.   Note:  Since there is no current is flowing inside

Chapter-4|Moving Charges and Magnetism| NCERT 12th Physics: Solenoid: A solenoid is a insulated long wire closely wound in the form of a helix. Its length is very large as compared to its diameter. In television, we make use of solenoid to generate magnetic field needed for the deflection of electron in the picture tube. Magnetic
