The equation for the force on the wire is given as F=BIL, where B is the strength of the magnetic field, I is the current in amps and L is the length of the wire in and perpendicular to the field.
The magnetic field within a solenoid can be quite large since it is the sum of the fields due to the current in each individual loop. We grasp a section of wire with our right hand pointing the thumb ...The magnetic field within a solenoid can be quite large since it is the sum of the fields due to the current in each individual loop. We grasp a section of wire with our right hand pointing the thumb in the direction of the current flow and our fingers will curl around the wire in the direction of the magnetic field. If a piece of iron is placed inside the coil of wire, the magnetic field is greatly increased because the domains of the iron are aligned by the magnetic field of the current.
