Explain magnetic field and magnetic forces, and give examples in daily life.
not by hand please and do not copy others work from chegg.
Thanks.
Magnetic field:
The space or region around a magnet within which a magnetic force is exterted on other magnet is called as magnetic field. Like a bar magnet will attract the piece of iron when it placed under its magnetic field. It expressed in unit of Tesla.
A moving charge is also the source of creating a magnetic field. When a charge move, it will also create the magnetic field around it.
Some Real life examples of magnetic field are:
1. A current currying wire on the stress or home.
2. Magnets are used to make a tight seal on the doors of refrigerators.
3. Many computers use magnets to store data on the hard drive.
4. Magnets in the electrical generator turn mechanical energy into electricity while some motors convert electric energy into the mechanical work.
5. Mines uses magnetic sorting machine to seperate useful metallic ores from crushed rocks..
Magnetic force:
It is the force of attraction or repulsion Between charged particle due to their motion. The Magnetic force between two moving charges may be described as the force exerted upon by their charge by the magnetic field created by the other. This force cause magnet to attract or repel one another.
The magnetic force depend upon the velocity of the charge, magnitude of the charge and value of the magnetic field of the magnet under which it is moving.
Examples are:
1. A combination of generators + motors. The forces acting in the AC/DC motors due to which they rotate are magnetic force.
2. A speakers for sound are work due to magnetic force.
3. Particle accelerator work on this principle.
4. A fan which you are using day to day life are based on magnetic force.
5. A small crane in the workshop which used to attract object using elecctro magnet.

Explain why iron filings align to give the appearance of field lines when in a magnetic field How was the Gilley coil's magnetic field affected when the iron core was? (Hint: see Figure 2) Figure 2: As the magnetic field strength (H) increases from zero (a), the magnetic domains that are aligned parallel to it increase in size at the expense of their neighbouring domains (b), then whole domains start to switch (c) until all domains are aligned (d). Explain...

Can a magnetic field do work on a charge? yes no The half-life of 14C is 5730 years. Explain how we can use this information to estimate the age of wood samples found in ancient campsites. Be explicit. Suppose the wood from an ancient campsite contains 1/128 of the 14C found in a present day sample. How old is the wood?
