Explain how magnetic forces enable a maglev train to float above the tracks. and hurry it’s timed

The magnetic forces enable a maglev train to float above the tracks due to the repulsion property of the similar magnetic poles.

Explanation:

The maglev trains consists of a guide-wave which is made up of a network of conventional electromagnet or superconducting element.

The conventional electromagnet with high energy in the guide-way will repel the magnetic poles present below the maglev trains when the current is passed.

As electromagnets attain magnetic energy in the presence of high amount of current, more energy is required for conventional electromagnet guide-ways used maglev trains. But the electromagnets cause repulsion with the magnetic in the bottom of maglev trains leading to floating of the trains on the track or guide-ways.

For superconducting guide-ways, it require less energy compared to electromagnetic guide-ways but very low temperature should be maintained.

As at low temperatures, superconductors will repel the magnetic field due to Meissner effect, it will expel the magnetic flux density thus leading to floating of maglev trains.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
