[@kumaramit922]

Dear Suman..one thing i have noticed that what u r saying is, in the presence of external magnetic field applied by the machine the spin of protons oriented in alpha state that is most stable state and then we will apply some electromagnetic radiation to convert in beta state..I think that is not true..In the absence of magnetic field(under the earth magnetic field) the magnet are randomly oriented in any direction. But when you apply external magnetic field by NMR machine it will oriented in two direction alpha and beta state..and since accorting to Boltzmann distribution law the molecules in alpha state is little more then beta state. When we will applied radio frequency the alpha spin state flips ito beta spin state and the process is called as resonance.

[@rashhuparmar2851]

I have studied shielded protons need a stronger applied field to produce the absorption signal.. u r telling that shielded protons require less energy... pls clear my doubt let me know where wrong iam going..?

[@observablesasscience1208]

It depends on the type of machine.If you are keeping magnetic field strength constant, shielded proton requires only less amount of energy (remember magnetic field is constant here).We are mostly using this type of machines.Other type is just vice versa....But we don't build machines that has both field and energy as dynamic variable.

[@vishalkatoch3791]

You are right!! that's why they are called shielded protons because you need more energy to degrade their charge cloud!! Chodu's Biology is wrong here as he is in most videos...

[@neethumani8728]

Even I hv the same doubt

[@sanskritiladiya828]

I agree with you.. same doubt🙄

[@pragathiraghavender1843]

But here we need to note that the shielded protons need less energy because their magnetic power gets covered with electrons and hence the energy applied to spin it to the opposite direction (repulsive forces between same poles) would be obviously less.

[@avinashrai5075]

Actually poles of earth is a opposite to magnetic poles, we take pole at which north pole of magnetic needle points as a north pole, but about the above video there should be direction of external magnetic field should from north to south pole...because outside the magnet magnetic field is from north to south pole.

[@rupambikadas4929]

why less energy is required for shielded ?Did not understand the concept

[@nandhinikp5296]

The hydrogen atom is shielded due to more electrons from other atoms around it and hence the magnetic power is automatically reduced due to the shielding. If the magnetic power is less around the hydrogen, then less energy is enough to do the beta spin.

[@onslaabidi5254]

when the hydrogen is schielded ,the effect of the magnetic field will be reduced and for example instead of turning the hydrogen in 180 degres u'll just need to turn it in 60 degres to reach the resonance position and thus u'll need less energy

[@sovietdominic9649]

thanks

[@imrocknreeling]

Rupambika Das because electrostatic interaction are quite high, so because of the interference which is already there, spin requires less energy to rotate that proton. Thank me later.
