Can a Planet's Electromagnetic Field Be Strong Enough for Wireless Electricity (Induction)?

Wikipedia states:
"ElectromagneticÂ orÂ magnetic inductionÂ is the production of anÂ electromotive forceÂ (i.e., voltage) across anÂ electrical conductorÂ in a changingÂ magnetic field."

This one sentence has baffled me and raised more questions than answers. As I would strongly prefer to not have to learn an entire field of science, I decided it was time to post a question on the topic.

Is it possible to build a device capable of charging electronic devices by using the planet's electromagnetic field as an energy source? Is there any situation in which this might be possible, even if unlikely?

Good answers will tell me why or why not this is possible, and a "electromagnetic induction for dummies" rundown would be appreciated as well.

Bonus points to someone who can calculate how strong of an electromangetic field a planet would need to make this possible. (if even possible)
