I need to calculate force between Permanent magnet (NdFeb) and electromagnet for different voltages(5-24). They are 5 mm apart in the device.
Currently I had measure the Magnetic field for Permanent magnet in terms of Magnetic Fled Vs Distance (197 mT at 5 mm) and for electromagnet in terms on Magnetic Field Vs Voltage (134 mT for 12V at contact).
Any suggestions will be highly appreciated.
Thanks in advance.
