Homework Statement
To determine a formula that can be used to determine the lifting capacity of an electromagnet/magnet through a known air gap.
Homework Equations
Weight= (magnetomotive force)/reluctance
The Attempt at a Solution
From the experiment the following general observations were made with respect to the lifting capacity of the electromagnet.
Lifting strength increased as # of turns doubled, current doubled and size of core doubled, however decreased as air gap increased.
By using the equation:
Effect= Cause/Opposition
Where the desired effect is to overcome the object weight
the cause is the magnetic force produced by the magnet
the resistance to the magnetic flux due the the air gap.
Weight= (magnetomotive force)/reluctance
Weight= BlIsinθ/(l/μA)
