I have 2 iron cores with 10mm dia x 20mm length. with a coil with 500 turns of 0.3mm wire thickness, i guess i can pass 0.2 Ampere through that wire. The maximum distance between these 2 electromagnets is 15mm and minimum is 2mm

Yes that 20 is actually 20 degrees. should i convert it into radians which is 0.34906585 radians ?

No its in my engineering design problem. I am just stuck here. I need to plot the graph for theta as a function of time. I am not really good in calculus to be honest. May be i can use MATLAB to solve !

Kindly can someone tell me how can i integrate and plot the following formula as a function of time. while theta is changing from 1 to 20. also attached .docx file for convenience. Any kind of help or advice will be highly appreciable.

I need to make an electromagnet with maximum 20mm dia including winding. I have an iron core of 10mm dia and 20mm length. I can't decide - which wire to choose, - what no. of turns should i provide - how much current should i pass through the wire. - what should be the voltage. Any help and...

I am looking forward to know how to calculate the force between 2 electromagnets. what is the formula to find attraction and repulsion forces between them ? Thank you.
