of the turns in the coil add together‚ so the total magnetic field is much stronger. This produces a field which is similar to that of a bar magnet. A coil of wire like this is often called a solenoid. http://www.bbc.co.uk/bitesize/standard/physics/using_electricity/movement_from_electricity/revision/1/slideshow-1/2/ An electromagnet consists of a coil of wine‚ through which a current can be passed‚ wrapped around a soft iron core. This core of magnetic material increases the strength of

Helicopters Back in the 1500’s there was a renaissance man named Leonardo Di Vinci‚ this man was the first man to develop and draw the idea of a machine that is capable of vertical flight‚ which we now know as a helicopter. His design would have worked‚ but only theoretically. Many others tried but were missing two things‚ the understanding the nature of lift‚ and an engine. At the end of the nineteenth century‚ the internal combustion engine made it possible for the development of full sized

The essential part in this practical is to plan the experiment in detail in order to obtain substantial data. Firstly we have to identify our controlled variables which will be kept constant throughout the experiment. By carrying out this practical it

According to the Hemingway App‚ my literacy narrative is pretty hard to read. I was surprised by this since I thought it was a pretty easy to read paper‚ and flowed well. It said I used way too many adverbs‚ but there were also no instances of me using a passive voice. In my Wordle‚ the biggest words I saw were: opponent‚ sparring‚ sword‚ training‚ Isaiah’s‚ Isaiah‚ match‚ year‚ and win. I remember using most of these words pretty often and I’m not surprised that they came up. There is an idea that’s

Helicopter Parenting Taking care of children can be bad for a family. The relation in a family might depend upon how much time they spend with each other‚ but it become worse when parents are not aware whether what they are doing is reasonable for everyone in the family or not. The act of taking care of children closely‚ or “helicopter parenting”‚ is not common for modern societies. Helicopter parenting has a negative consequence to families because children may be unable to have positive thinking

Some helicopter parents mat even cross the line into unethical areas such as school parks to make sure nothing happens at school. Also helicopter parents

Theory behind my experiment Thickness (cross sectional area of the wire)‚ length‚ and temperature all have some effect on the amount of resistance created in a wire. Another factor is the conductivity of the material we are using. Some metals are just more electrically conductive than others. As long as I use the same type of metal for each wire‚ my experiment will remain fair. Cross Sectional Area The thicker the wire‚ the less resistant it is. This is because there are more electrons
