electromagnet is a soft iron core placed in a solenoid . They are temporary magnets whose strength can be increased by increasing the flow of current in the solenoid.
Fleming's right/left hand rule states that if we keep our thumb of right/left hand perpendicular to forefinger of same hand and the middle finger perpendicular to the forefinger of same hand, then the thumb will point towards the direction of force, forefinger will point towards direction of magnetic field & the middle finger will point towards the direction of flow of current
