CBSE Class 10 Physics Magnetic Force

• How the Fleming right hand rule is applied  
• Show with the help of an activity that a force is exerted on the current carrying conductor when placed in a magnetic field.
• List two factors on which the strength of the magnetic field lines produced by a solenoid depends.
• How can the direction of force on a current carrying conductor placed in magnetic field be reversed?
• What is the function of commutator ring in a motor?
• According to the Fleming's left hand rule what does the first three fingers of the left hand positioned perpendicular to each other represents?
• On what principle does electric motor works?
• A beam of electrons is passing a magnetic field at right angles as shown in figure. What would be the direction of force and which rule would you apply to find direction of force?
• If a magnet is brought near a current carrying conductor free at one end, would the wire move?
• When is the force on a current carrying wire maximum or minimum?
