FAQs on Force on Current Carrying Conductor Video Lecture - Physics Class 12 - NEET

1. What is the force on a current-carrying conductor in a magnetic field?
Ans. The force on a current-carrying conductor in a magnetic field is given by the formula F = BIL, where F is the force in Newtons, B is the magnetic field strength in Tesla, I is the current in Amperes, and L is the length of the conductor in meters.
2. How does the direction of the current affect the force on a conductor in a magnetic field?
Ans. The direction of the current determines the direction of the force on the conductor. According to Fleming's left-hand rule, if the current flows perpendicular to the magnetic field, the force is at right angles to both the current and the field. If the current flows parallel or antiparallel to the magnetic field, there is no force on the conductor.
3. Can the force on a current-carrying conductor be used to move it?
Ans. Yes, the force on a current-carrying conductor in a magnetic field can be used to move the conductor. This principle is utilized in devices such as electric motors, where the force exerted on the conductors causes them to rotate, converting electrical energy into mechanical energy.
4. How can the force on a current-carrying conductor be increased?
Ans. The force on a current-carrying conductor can be increased by increasing the current, the magnetic field strength, or the length of the conductor. Additionally, the force can be maximized by ensuring the conductor is perpendicular to the magnetic field.
5. What are some practical applications of the force on a current-carrying conductor?
Ans. The force on a current-carrying conductor in a magnetic field has various practical applications. It is used in electric motors, generators, and transformers to convert electrical energy into mechanical energy or vice versa. It is also utilized in devices such as loudspeakers, headphones, and magnetic levitation systems.
