Moving Charges And Magnetic Fields
Moving Charges And Magnetic Fields
You can see the shape of the magnetic field established by the current by running a straight wire vertically through a sheet of paper. The wire is connected to a battery, and iron filings are sprinkled on the paper. The filings will become aligned as each tiny piece of iron is moved parallel to the field. Overall, filings near the wire form a pattern of circles with the wire in the center.
A current-carrying wire that is formed into a loop has circular magnetic field lines that pass through the inside of the loop in the same direction. This has the effect of concentrating the field lines, which increases the magnetic field intensity. Since the field lines all pass through the loop in the same direction, one side of the loop will have a north pole and the other side a south pole.
Many loops of wire formed into a cylindrical coil are called a solenoid. When a current passes through the loops of wired in a solenoid, each loop contributes field lines along the length of the cylinder. The overall effect is a magnetic field around the solenoid that acts just like the magnetic field of a bar magnet. This electromagnet can be turned on or off. In addition, the strength of the electromagnet depends on the size of the current and the number of loops. The strength of the electromagnet can also be increased by placing a piece of soft iron in the coil.
A solenoid can serve as an electrical switch or valve. It can be used as a water valve by placing a spring-loaded movable piece of iron inside the wire coil. When a current flows in such a coil the iron is pulled into the coil by the magnetic field, turning the hot or cold water on in a washing machine or dishwasher, for example. Solenoids are also used as mechanical switches on VCR's automobile starters, and signaling devices such as door bells and buzzers.

Disadvantages of Home Schooling
Disadvantages of Home Schooling
If you are concerned about the education your child is receiving at either a public or private school, you may have considered the option of home schooling. There are many advantages to home schooling that are easy to think of, but in making your decision you must also consider the disadvantages. Yes, despite all the bonuses you can think of in home schooling your child, there are many disadvantages to the process.
Home schooling is a process that requires a massive amount of time and dedication. If you want to home school your child you must be present for a large part of the day. Kids are kids. Depending on how motivated by academic success your child is, he or she may not require constant supervision. However, in many studies, parental supervision is the key behind the success of home schooling programs.
Parents must also possess instructional skills or access to someone who can teach effectively. Simply putting your child in a room with textbooks will most likely result in home schooling failure. In addition, you will have to purchase materials that public and private schools provide for students.
There is also the need to be able to serve as guidance counselor as your child may require specialized instruction due to a learning disability. Public and private schools usually provide these services with qualified individuals.
One important benefit of an academic institution is the opportunity for children to become properly socialized. Attending school with other children from all walks of life leads to the development of social skills. One of the disadvantages of home schooling is the relative isolation children have from their peers.
Many parents find comfort in blaming the educational system for the shortcomings in their child's academic performance. If you choose to home school you will be accepting full responsibility for the outcome of your child's education. This is more of a burden than it seems. Studies have shown that many home schooling ventures fail due to the fact that the home generally lacks qualified educators. Many parents have gripes about teachers, but the fact is that they generally have to teach large classes filled with children with diverse learning needs. In addition, certified educators have taken teaching classes and have passed state examinations to receive their teaching certificates.
When you approach the issue of home schooling you must examine both sides. Sure, there are plenty of advantages, but if you forget to look into the disadvantages, you may be setting yourself up for failure.
