Why do AA batteries seem to make an electromagnet stronger whereas a 9 volt isn't as effective? - strongest aa batteries
It seems that when using a AA battery to an electromagnet power, much stronger than a 9-volt battery used to power the electromagnet itself seems, can you tell me why?

If you could measure the voltage in the electric stress to reach the Imam of the 9V battery is lower than the AA battery. The 9V battery is a 6-cell, 1.5V batteries connected in series. The internal resistance of the cells are short, and reduces the available voltage at high current () as an electromagnet. Not only the AA battery cell in a monkey (the 1 / 6 of the internal resistance of the 9V battery), the volume is much higher than the volume of 1.5 volts of battery cells 9V. The power supply capacity of the internal resistance rises and falls technically with the cell volume (in the area of electrode), allowing the cell to provide better high currents.
Since the 9V battery is saturated with the electromagnet, and became a short circuit. Remove the core of the electromagnet and try ........
