Does Lenz's law violate the principle of energy conservation?

Describe briefly, with the help of a lablled diagram, working of a step-up transformer. A step up transformer converts a low voltage in to high voltage. Does it not violate the principle of conservation of energy?

Define Lenz's law.

State the principle of conservation of angular momentum.

Is Lenz's law in accordance with the law of conservation of energy?

Lenz's law is a consequence of the law of conservation of

Lenz's law is a consequence of the law of conservation of:
