But don't you think this method could improve the power transfer efficiency. Currently, wireless chargers are only 75% efficient. Maybe Halbach arrangement could improve up to 85-90% since the majority of the magnetic flux in one direction. Maybe there could be an increment inefficiency? I...

I want to use inductive or magnetic resonant coupling concept using a series of capacitors in the coil. The frequency is between 100-200 Khz. The distance between the tx and rx is between 5mm to 20mm distance. I want to transfer 15 watts and try charging a smartphone. Let me know your suggestion.

My plan is to create a wireless power transfer using halbach array configuration. Since halbach gives strong magnetic field, this mechanism may help to improve the efficiency. let me know your thoughts.

Can we arrange solenoid in Halbach arrangement with few numbers of turns and achieve the result that I need? We know solenoid behave similarly to the permanent magnet. Just a thought.

I have read this before but it's not mentioned what supply was given, I think most probably DC current. My question is that what happens if we give pulsed DC to this concept because Pulsating DC doesn't change direction. Will, there be any eddy current problem between the coils?

Thank you for answering. I mean that I want to use Halbach configuration using coils. I'm thinking to arrange solenoid in Halbach array arrangement to give strong flux in one side and weak in the other side. We know that solenoid behave similarly to the permanent magnet. Since alternative...

Can we use Halbach array for the electromagnetic field since the magnet field change with direction? What would be the disadvantage? Imagine if we use Halbach array special arrangements for the transformer instead of an iron core. Maybe it could give us the same result? Kindly Maybe we can...
