Magnetic Levitation: School Experiment

Magnetic levitation uses magnetism to suspend an object in the air. It counters gravity and any other vertical acceleration or deceleration factors.  Two primary forces are involved. The first lifts the object with sufficient force to counter gravity. The second ensures stability, so it cannot slide sideways to neutralize the lift.

Commercial Applications for Magnetic Levitation

Magnetic levitation enables movement of an object without friction, by virtue of gravity not pressing in down onto a surface.  The concept is proving popular for public transport, since higher speeds are possible using less energy.

In theory, speeds of up to 4,000 miles per hour are possible, provided engineering – and passengers – could survive the strain. The Japanese Maglev beat all records in 2015 with 375 miles per hour. The Hyperloop may do better because sideways movement is more manageable inside a tube.

Here’s a Neat Experiment to Illustrate Magnetic Levitation

How Magnetic Levitation Could Shape the Future

Scientists are working in overdrive to exploit the possibilities. Some ideas are practical, while others are not. A Chinese architect suggested a sky island housing a city floating above the earth to relieve population pressure. This proved impractical.

However, we like the idea of wind turbines in the sky where the wind blows stronger. This could lower the cost of wind energy and even generate electricity for a million homes someday.

We wrote this post to challenge conventional thinking. Because we are stuck in a transport paradigm where we have to move from A to B along a road or rail or sidewalk, unless we queue for ages at an airport first. We don’t have a solution for intensive private drones yet.

However, a sky taxi riding in the sky on batteries and magnetic levitation, and landing in the street outside to pick us up could prove a possibility. Do you think this is a good idea: What else do YOU think we should do?

I tripped over a shrinking bank balance and fell into the writing gig unintentionally. This was after I escaped the corporate world and searched in vain for ways to become rich on the internet by doing nothing. Despite the fact that writing is no recipe for wealth, I rather enjoy it. I will not deny I am obsessed with it when I have the time. My base is Umtentweni in South Africa on the Kwazulu-Natal South Coast. I work from home where I ponder on the future of the planet, and what lies beyond in the great hereafter. Sometimes I step out of my computer into the silent riverine forests, and empty golden beaches for which the area is renowned.
