As you increase current, what happens to the strength of an electromagnet?

Two firefighters are fighting a fire with identical water hoses and nozzles, except that one is holding the hose straight so that the water leaves the nozzle in the same direction it comes, while the other holds it backward so that the water makes a

A 55-kg mountain climber, starting from rest, climbs a vertical distance of 701 m. At the top, she is again at rest. In the process, her body generates 4.5 * 106 J of energy via metabolic processes.
