Presentation transcript:

How The Faraday Motor Works Long freely hanging wire N The conducting wire is hanging vertically so the vertical component of the bar magnet’s field plays no part. It is only the horizontal component of the field which is perpendicular to the current

How The Faraday Motor Works Long freely hanging wire current direction Horizontal component of the field of the magnet. N

How The Faraday Motor Works current direction thrust Horizontal component of the field of the magnet. N By Fleming’s left hand rule the thrust on the wire is “into the board”at rigt angles to both the current and field

The Shape Of The Field The field is not uniform but is distributed radially around the bar magnet As seen from above So the wire rotates around the bar magnet
