thank you so much for your reply. I've used the equation of magnetic field along the axis of the solenoid. I've to measure the field at a distance (>=2 mm) from one edge of the solenoid. at this distance the field get reduced than the center of the solenoid.
Increasing number of turns is not...
Hi, I am working on a project where I've to make an electromagnet and very very low amount of current (micro amp to nano amp) will be supplied to the electromagnet. And finally have to measure the magnetic filed with a sensor.
My question, is it feasible to generate measurable magnetic field...
