Electric and Magnetic Forces: Electromagnetism

Science ObjectDigital resources are stored online in your NSTA Library.

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the last of three Science Objects in the Electric and Magnetic Forces SciPack. It explores magnets, magnetic forces, and the relationship between magnetic and electric forces. Magnetic and electric forces are closely related and can be thought of as different aspects of a single electromagnetic force. Both electric and magnetic forces are thought of as acting by means of fields: an electric charge has an electric field in the space around it that affects other charges, and a magnet has a magnetic field around it that affects other magnets. Moving electric charges produce magnetic fields and are affected by magnetic fields. More generally, a changing electric field induces a magnetic field, and vice versa. This interaction is the basis of many natural phenomena. For example, electric currents circulating in the earth's core give the earth an extensive magnetic field, which we detect from the orientation of our compass needles. The interplay of electric and magnetic fields is also the basis for electric motors, generators, and many other modern technologies.

It all comes together in this final third of the Electric and Magnetic Forces series. I wish I had this resource years ago!!!

I really enjoy Science Objects. In 1-3 hours, the Electric and Magnetic Forces: Electromagnetism Science Object will help me re-learn, refresh, or learn for the first time some critical science concepts I will have to know to obtain my Science Educator credentials. I appreciate that I can complete them at my own pace, and that, if used as park of a SciPack, I have access to a content expert to go to for help. The NSTA Learning Center Science Objects are really beneficial!

This resource and the ones like it are particularly valuable for me for several reasons. First, I like the table of contents off to the left, which all ow me to keep track of what is coming up and see the entire lesson at once. Also, it is multisensory..enaging several senses. Finally, they are self paced, which I really need with my busy lifestyle.

I loved the reviews in this Science object! The examples used in this object were very informative and interesting, actually. They are all things that even the kids would be excited to learn about. This is a great way to introduce a topic of curiosity and fuse it with good, relatable examples that would nail the content in.

This topic is provided with good examples and probing questions that help the students to think deeper. A good resource that could be developed and administered for different levels of students.
