The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field.
'What effects the strength of an electromagnet?' Introduction: An electric current flowing through a wire produces a magnetic field. Coiling the wire produces a stronger magnetic field. Coiling it around a soft iron core increases the strength effect; raising the current or the number of coils increases it further.I am going to investigate the raising of the current and how it affects an electromagnet.I think the electromagnet will produce a stronger magnetic filed and pick up more iron fillings. Aim: To investigate factors which affect the strength of the electromagnet and make the strongest electromagnet possible. am going to investigate the raising of the current and how it affects an electromagnet.
