Introduction With the rise in the aging population, there has been an increase in demand for implanted medical devices, such as pacemakers. Approximately, 70% to 80% of all pacemakers are implanted in people 65 years old or over (Bradshaw, Stobie, knuiman, & Briffa, 2014). Lithium batteries have dominated as the main source of energy for implantable medical devices. The limitations of lithium batteries have become apparent. The batteries have a limited energy capacity; therefore, this limits its

Transportation is the process of which people get from one location to another; however, it comes at a cost. The price we all pay when we take a method of transportation comes in two forms. The first form is time and the second is a monetary value. In recent days it seems like the cost that correlates to transportation is rising. As raw materials like oil and coal become scares throughout the world the price for those materials increase as the demand increases. With the cost of raw materials increasing

Upon the first discovery of electricity, the subjects of electricity and magnetism would go on to revolutionize life as we know it. With the rudimentary work completed by the leaders within the field, such as Benjamin Franklin or Nikola Tesla, these brilliant scientists laid the foundation that would go on to become arguably one of the most important aspects of our forever-changed society. Although we have learned to incorporate electricity, it has many uses within our lives. Electric energy is at

A north pole and a south pole of two magnets pull together in a tight line. It takes a hard pull to rip them apart. It’s common knowledge. Opposites attract. How could such polar opposites pull together so tightly? Well, logically, opposites are able to make up for what one part may lack in. In William Shakespeare's “Romeo and Juliet”, a play around a tragic love between two teenagers, Lady Capulet, elegant and distant mother, and the Nurse, vulgar but kind caretaker, serve as a dramatic foil in

Magnetic Fields An electricity and magnetism phenomenon apparently unrelated to power are electrical magnetic fields. We are familiar with these forces through the interaction of compasses with the earth's magnetic field, or through fridge magnets or magnets on children's toys. Magnetic forces are explained in terms very similar to those used for electric forces: * There are two types of magnetic poles, conventionally called North and South * Like poles repel, and opposite poles attract

When Benjamin Franklin first discovered electricity, it was one of the biggest discoveries known to mankind. Even though our dependence on electricity is enormous, it is still easy to forget just how dependent we are on electricity. Electricity has played a huge part in our everyday lives and will continue to do so. In fact, it is quite hard to imagine humanity without electricity. When it comes to transportation, electricity will someday rewrite the history books. One of the most important

Magnetics fields of Magnets with different orientations were observed. For its first subpart A. Like poles of bar Magnets, the magnetic fields are attracted to their opposite poles, thus it is shown that the magnets repel each other. For the next subpart B. Unlike poles of bar Magnets. The magnetic field lines of the North-pole is attracted to the South-pole. This is why in the figure, it can be seen that the two magnets are seeking each other. For subpart C. Two U-magnets with their unlike poles

using extremely cold magnets. People also want to know more about them as they become more popular! Repeated experimentation by experts say that if the magnet is cold, the strength of it will go up. To understand this, you need to know about magnetism, temperature, and magnetism strength. Magnetism occurs when a magnetic field forms. There are two sides of a magnetic field; south pole and north pole. If the two poles are opposite, they will attract and vise versa. A magnet can magnetize an iron

the bar magnet until you’ve put it on the opposite side of the bar magnet. Describe what happens to the compass needle. The white lead of the needle faces the South part of the magnet in a perpendicular way. When the needle is facing the center of the magnet, the lead turns to a 90 degree angle, being parallel to the magnet. When the compass faces the North part of the magnet, the needle turns 90 degrees in the same direction until the red lead if facing towards the North of the magnet.

have with respect to the permanent magnets. Introduction Linear generators/motors have been around since the early 1900’s with one of the first written references being in regard to Birkeland’s Cannon, then described as a tubular motor but is more accurately described as a reluctance motor. 1 Today linear generators/motors have more widespread, not to
