FAQs on Force on a Current Carrying Conductor in Magnetic Field Video Lecture - Science Class 10

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, B is the magnetic field strength, I is the current flowing through the conductor, and L is the length of the conductor within the magnetic field.
2. How does the direction of the force on a current-carrying conductor depend on the magnetic field?
Ans. The direction of the force on a current-carrying conductor depends on the direction of the magnetic field as well as the direction of the current. According to Fleming's left-hand rule, if the thumb of the left hand points in the direction of the current and the fingers point in the direction of the magnetic field, then the palm will indicate the direction of the force.
3. What happens to the force on a current-carrying conductor if the current is increased?
Ans. If the current flowing through a conductor is increased, the force on the conductor will also increase. This is because the force is directly proportional to the current. Therefore, doubling the current will result in the force being doubled as well.
4. How does the length of the conductor affect the force on a current-carrying conductor in a magnetic field?
Ans. The length of the conductor within the magnetic field affects the force on the conductor. If the length is increased, the force will also increase, assuming the current and magnetic field strength remain constant. This is because the force is directly proportional to the length of the conductor.
5. What happens to the force on a current-carrying conductor if the magnetic field strength is increased?
Ans. If the magnetic field strength is increased, the force on the current-carrying conductor will also increase. This is because the force is directly proportional to the magnetic field strength. Therefore, doubling the magnetic field strength will result in the force being doubled as well.
