# Calculation of magnetic force on a wire

 P: 123 Hi, I would like to know if it is possible to move a steel wire against frictional forces using a magnet. What would be the approach of calculating the force acting on that thin wire. I would know the dimensions of the wire and the dimensions of the magnet. What other values should I find from data table. Thanks Rupak

It is - you can easily see this with any handy magnet and a bit of wire since all normal situations involve friction to some extent.

Same as any force calculation - or you could measure it directly.
 I would know the dimensions of the wire and the dimensions of the magnet. What other values should I find from data table.
Which forces do you need to calculate?
Take a look at the equations and definitions of the forces and see.
 P: 660 You can definitely attract steel with a magnet, but the force is seriously complicated to compute. Don't hope for anything like B*I*L. It depends on how the wire's permeability deforms the field.
