Justify your answer.Simple Electromagnet iron nail coiled wire wire Battery battery 1ector Stock Ter anN e) A physics teacher takes some of the wire used to create the given circuit and uses it to make an electromagnet by wrapping it around an iron core and connecting it to a voltage source. Describe one way to increase the strength of the electromagnet.
- A student is asked to build and demonstrate a working temporary magnet called an electromagnet. The student is very confused on which items to use to create a temporary magnet. Choose the best items the students should use to create the electromagnet. iron nail with warniron nail with copper wireplastic spoon with yarnplastic spoon with copper wireWith the use of examples, compare and contrast electric fields and magnetic fields. Be sure to include relevant equations, graphs, and diagrams to support (but not replace) your answer.Select all of the following descriptions that match what happens when a ferromagnetic material is placed in an external magnetic field. -The ferromagnetic material rapidly cools. -The external magnetic field induces magnetic poles in the ferromagnetic material. -The ferromagnetic material becomes magnetized. -The ferromagnetic material becomes positively charged. -The ferromagnetic material becomes negatively charged. -Nothing, ferromagnetic materials do not interact with magnetic fields.
- Two wires are connected to two different power supplies. The currents in the wires are shown in the diagram. Why are the wires attracted to each other?Physics 30 Forces and Fields Lesson 2 negatively charged rod Use the following information to answer the next question neutral electroscope to ground Ence positively charged rod neutral electroscope (name) h A student is investigating charging a neutral electroscope through induction and grounding. The student brings a negatively charged rod near the neutral electroscope then touches the electroscope to ground it. A student then brings a positively charged rod near another neutral electroscope then touches the electroscope to ground it. After grounding, the first electroscope will have a moved the ground hand, the second electroscope will have a because the electrons have moved the ground hand. The words that best fill in the blanks above, respectively, are A. positive, into, negative, out of B. negative, out of, positive, into, C. positive, out of, negative, into D. negative, into, positive, out of to ground charge because electrons have chargeif a permanent magnet picks up steel paper clip the paper clip also becomes a magnet . how does an electromagnet differ from the magnetized paper clip
