Designing microgenerator with Ansoft Maxwell

[jahedcuet]

I am designing an energy harvester consisting of a magnetic spring.
The figure is given in the attachment.
I have done the magnetostatic analysis (using Ansoft Maxwell 2D). But, now I am facing problem with -

• Force vs displacement curve of the moving magnet
• To calculate the output power (Voltage+current) from the winding arround the magnetic spring

I need to design a magnetic spring with highest linearity (linear force-displacement curve) and to get better power output from the winding.
I am beginner with ansoft maxwell. Can anyone help me in this regard?

Thanks

I have also a similar problem with Ansoft Maxwell !

This paper 'Design of a linearized magnetic spring for body-worn inertial energy harvesters' may help you out.
Thanks.
