Why Does More Current Make an Electromagnet Stronger
A bigger current will make a stronger magnet. Provided a steady current flows through the material at constant temperature the resistance remains the same. Is An Electromagnet Stronger Than A Normal Magnet Quora Now it also adds resistance in the wire so the current does slowly decrease as you increase the number of coils. . The simple idea here is that the iron becomes magnetised so that now not only do we have the magnetic field due to the electric current passing through the coils of wire but also the additional field due to the magnetised iron. Why is it that the more coils you add to an electromagnet the stronger its magnetic field is. Follow this answer to receive notifications. The strength of an electromagnet is determined by current. Modified 3 years 1 month ago. You can make a temporary magnet by stroking a piece of iron or steel such as a. When the electromagnet has a core of ferrous metal a poi...
