Electromagnetism

What does Len’z Law state?

The induced current in a conductor due to a changing magnetic field flows in a direction that opposes the change in magnetic flux

How does Len’s Law affect a magnet approaching coil?

The induced current created a magnetic field that opposes the magnetic field motion, slowing it down

What is Lorentz force?

The combination of the magnetic and electric force acting on a point charge due to electromagnetic fields

How does Lorentz force relate to MRI effects?

The interaction between the MRI static magnetic field and electrical currents in the body may cause psychological effects like dizziness or nausea

What does faradays law describe?

A changing magnetic field induces an electromotive force EMF in a conductor

How is faradays law applied in MRI?

The procession of protons in a magnetic field creates a changing field that induces a current in the receiver coil crucial for imaging

What does the empire Maxwell law explain

Magnetic fields are generated, not only by conduction currents, but also by changing electric fields (displacement current)

why is the empire Maxwell law sign significant?

It helps explain electromagnetic wave behavior, and is a key part of Maxwell‘s equations
