This is a question relating to the construction of the electromeagnet spcifically the core: Ive read that using a 'soft' iron core has low remnance, high permeativity and is relatively inexpensive. Can anyone recommend a different core material or possibly comment on the use of the soft iron...

Thanks for the reply rsr_life I couldn't find anything on how to compute/measure the magnetic field of an electromagent but I am going to go find a physics lecturerer today and see what he/she has to say on hte matter. I haven't decided on the core yet but since the electromagnet only has to...

Hi everyone Im an engineering student currently working on a group project. Part of the project is to use a electric magnet and a permanent magnet to balance a weight on the end of a cantilever (digital scale effectively). We would then measure the current through the electromagnet to...
