What else can I help you with?
What is the importance of the alternating magnetic field?
to move things energy alternatively
What does not create a magnetic field?
A great many things do not create magnetic fields. They includerock,plastics,most living things,most gases at normal conditionsActually most living things create magnetic fields measurable and commonly called brain waves. minute but measurable
The Earth's magnetic field helps protect living things from?
From solar radiation and cosmic rays
What does earths magnetic field help protect living things from?
Earth's magnetic field helps protect living things from harmful solar radiation and charged particles emitted by the sun, by deflecting them away from the planet. This shielding effect reduces the risk of genetic mutations and cellular damage that could be harmful to living organisms.
What is the importance of the each magnetic field?
The single biggest benefit to the Earth's magnetic field is that it shields the Earth's surface from harmful radiation.
Can things hover in a magnetic field?
Yes, certain objects can be suspended or "hover" in a magnetic field due to magnetic levitation. This occurs when a magnetic force counters the gravitational force acting on the object, allowing it to remain suspended in mid-air.
What is stereoscopically?
uses a magnetic field; to view living cells
Why are things magnetic?
Things are magnetic when their atoms have aligned magnetic fields that interact with an external magnetic field. This alignment creates a net magnetic field in the material, causing it to attract or repel other objects. Materials such as iron, nickel, and cobalt are particularly magnetic due to the arrangement of their atoms.
What is the importance of radial magnetic field in moving coil galvanometers?
To produce a constant torque on the coil
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
What does the magnetic field of earth cause?
Among other things the aurora.
What three things needed to complete magnetic induction?
A changing magnetic field A conductor or coil of wire Movement between the magnetic field and the conductor (relative motion)
