The image shows that an electromagnet made with a 1.5-volt battery (on the left). How would the strength of an electromagnet be affected if you replaced its 1.5-volt battery with a 9-volt battery (shown on the right) while using the same nail and coil?

Question

if you replace it with something with much higher strength, the strength would increase a lot. the electromagnet is going to use as much strength as it can.
