You can throw all the objects in it and roll it around instead of holding the objects and they fall out of your hands/arms (if too much).
Magnetic flux density - It is the force acting per unit current per unit length on a wire placed to magnetic field at right angle.
It is denoted by B
unit of B is tesla (T)
The total no. of magnetic field lines passing through a area is called magnetic flux.
Magnitude of the magnetic flux - It is equal to the area of the surface and having perpendicular direction to the plane of the surface.
Its unit is weber (Wb)
Direction to the magnetic flux density - The direction is north pole to the south pole.
The magnetic field lines are known as lines of magnetic flux.
flux lines are not in direction of force but perpendicular.
