1. 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

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

3. 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

4. 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
