WebFor any given combination of current and magnetic field strength, the force is greatest when the direction of the current is 90° to the direction of the magnetic field. There is no motor effect force if the current and magnetic field are parallel to each other. The direction of a motor effect force can be found using Fleming's left hand rule. http://www.gcsescience.com/pme21.htm

At 400 meters it was at its maximum of 6.25 per quadrat and at the highest height of 1300 metres the fewest plants per quadrat were seen or altitude up to 700 metres appears to have no effect on the numbers of plants per quadrat but after this height there is a reduction in … WebThe motor effect.
