Science The direction of magnetic field around a straight conductor carrying current can be determined by____________ Fleming's left hand rule Lenz's law Right hand thumb rule Fleming's right hand rule The magnetic field produced due to a circular wire at its centre is_________ at 45° to the plane of the wire at 60° to the plane of the wire in the plane of the wire perpendicular to the plane of the wire A magnetic field exerts no force on________ stationary electric charge a magnet an electric charge moving perpendicular to its direction an unmagnetised iron bar At the centre of a magnet, the magnetism is____________ zero same as the poles maximum minimum Induced current flows through a coil__________ more that the period during which flux changes through it. less than the period during which flux changes through it only for the period during which flux changes through it None of the above Define the terms magnet and magnetism. Define natural magnet. Define artificial magnet Define right hand thumb rule Define Fleming's Left Hand Rule.
