Answer: Option D We can use Fleming’s Left Hand Rule to determine the direction of the force on the current carrying wire. The real reason is due to the combined magnetic fields of the current carrying wire and magnets (as shown in the diagram). The resultant magnetic field creates an uneven magnetic field around the wire. The direction of the force on the wire is in the direction from strong magnetic field towards the weak magnetic field region.

Alpha, beta and gamma emissions behave differently in electric field and magnetic field, depending on charge, mass and speed. In general, the charge of the particle will determine the direction of deflection, and the mass will affect how much deflection. In an electric field, due to laws of electrostatic (like charges repel, unlike charges attract) the charged particles of alpha and beta will be deflected in opposite direction. In a magnetic field, you can determine the direc

We are all familiar to applying FLHR to the current-carrying wire. But actually there is an equal and opposite force acting on the magnet too! Magnetic force is an action-reaction pair (Newton’s 3rd Law) View the video explanation What happens to the readings on the electronic balance when currents flow through the wire? https://youtu.be/6R32DsGNkic
