FORCE ON CURRENT CARRYING CONDUCTOR MAGNETIC EFFECT OF ELECTRE CURRENT 13 Class 10th Physics (Practice Sheet) 1 When a current-carrying conductor is placed in a magnetic field, a force is experienced by the conductor due to: A. Electric field B. Gravitational field C. Magnetic field D. Electrostatic field 2 The direction of the force experienced by a current-carrying conductor in a magnetic field is given by: A. Ampère's direction rule B. Right-hand thumb rule C. Left-hand thumb rule D. Fleming's right-hand rule 3 The SI unit of the magnetic field is: A. Joule B. Ampere C. Tesla D. Newton 4 A current-carrying wire is placed in a magnetic field. If the current direction is reversed, the direction of the force acting on the wire will: A. Remain unchanged B. Reverse direction C. Become zero D. Decrease 5 Two parallel current-carrying conductors attract each other when: A. The currents are in the same direction B. The currents are in opposite directions C. The currents are equal D. The currents are zero 6 What exactly do you mean by "current-carrying conductor"? 7 Explain why two parallel current-carrying conductors attract. 8 How can an Electric field be shielded by the Faraday cage effect? 9 How can the magnetic force of 50C charge particles traveling at 3m/s in a 1T magnetic field be calculated? Its field is pointing in the same direction as the path of the second particle. 10 What are magnetic flux lines what is the significance of magnetic flux? Page 1 Email: Phone No: Website:
