The strength of the magnetic field around a solenoid is directly proportional to the current.
Finn wanted to create a controlled magnetic field using the solenoid to use as an electromagnet. Finn obtained two strengths by varying the current in which, for the second case, the strength is more. The current in the first case is 49 units.
Q: Is it true that "The current flow in the solenoid coil for the second case could be 49 units."
