Is lifting an aircraft carrier possible with a magnet?

Is lifting an aircraft carrier possible with a magnet?

Yes, It is possible through a concept.

When assembled, the magnet will be 59 feet tall and 14 feet wide, weighing a thousand tons. It was built in the US and has been shipped to France to the experimental fusion reactor known as ITER.

The magnet will be capable of producing a magnetic field measuring 13 teslas — around 280,000 times stronger than Earth's magnetic field — making it strong enough to lift an entire aircraft carrier, which weighs around 100,000 tons (90,700 metric tons).

There is an international effort to build a fusion machine. When you heat things up enough the electrons become so energetic that they are lost and you are left with a plasma of charged particles. Because they are charged they can be manipulated by a magnetic field. Building the magnets to do this is probably the most challenging part of the fusion equation.

But that’s nothing

This large-bore, full-scale high-temperature superconducting magnet designed and built by Commonwealth Fusion Systems and MIT’s Plasma Science and Fusion Center (PSFC) has demonstrated a record-breaking 20 Tesla magnetic field. It is the strongest fusion magnet in the world.

The major innovation in the MIT-CFS fusion design is the use of high-temperature superconductors, which enable a much stronger magnetic field in a smaller space. This design was made possible by a new kind of superconducting material that became commercially available a few years ago.

45 Tesla’s – The Strongest Magnet of all

The measurement, achieved by researchers at the National High Magnetic Field Laboratory (MagLab) at Florida State University resets the bar on what's possible indirect current magnetic fields.

When some superconductors are chilled to within a degree or 2 of Absolute zero ( - 273 DegC) they can be used to make phenomenal magnetic fields. One problem with conventional superconducting circuits is that when they heat up, they can suffer from a sudden jump in resistance called quench. Any flaw or deviation in their path causes conduction to become less than super, interrupting the flow.
