Electromagnets
When building an electromagnet, this provides the electric current for the magnet.
What is a battery?
These three things make up the Electricity Triad.
What are Electricity, magnetism and motion?
A force of 10 newtons is acting upon a box. If the box is not moving, we can assume
What is there is a 10 newton force in the opposite direction?
Electric current will flow through a circuit as long as the
What is path is unbroken?
Newton’s Third Law of Motion is summarized as, “to every action and force there is a(n)
What is equal and opposite reaction and force?
This is what the metal center of an electromagnet is called.
What is the core?
Which two items of the electricity triad were needed to build a motor and how did you know your motor was successful
What is magnetism and electricity and we got motion?
120 Newtons of force are applied to a bowling ball with a mass of 6 kg and a baseball with a mass of 0.15 kg.
This will be the effect on each of these objects
What is the baseball will accelerate more than the bowling ball?
This would form a CLOSED circuit
What is a light switch being turned on?
Metals such as copper and silver have properties in common, such as the ability to allow electricity to flow through them easily. This property is known as?
What is electrical conductivity?
Electromagnets are used in many electric motors, generators, and simple devices. Electromagnets are much more useful than permanent magnets because unlike permanent magnets, electromagnets
What is can be turned off?
These items were needed to build your speaker.
What is a magnet, copper wire (coiled) and a cup or plate?
Luis is paddling his kayak upstream. The overall force from his paddling is equal to 156 newtons. The current from the river is equal to 455 Newtons.
This BEST describes the result of these forces.
What is the kayak will move backward with a force of 299 newtons
This would form an OPEN circuit?
What is a doorbell after it has been rung?
The “brightness” of the light from the infrared diode is constant?
What is false?
These things are needed to make an electromagnet
What is electric current, a wire and a metal core?
In an electric turbine generator an electromagnet interacts with a moving turbine to do this
What is turn motion energy into electrical energy?
If the current from the river stays the same but Luis paddles harder, increasing his force to 310 N, this will be the overall effect of the forces on his kayak.
What is the kayak will move backward with a force of 145 newtons?
(Imagine the light bulb to battery picture)
The circuit in the picture will?
What is cause the bulb to light?
What is a common use of infrared lights?
What is remote controls?
The BEST description for the relationship between magnetism and electricity in an electromagnet.
What is magnetic fields are created by the flow of electric currents?
This produces a magnetic field.
What is electricity moving through a wire?
Luis asks his friend Elise to pull his kayak with a rope from her car. She drives forward with a force of 2500 Newtons as he paddles forward with a force of 125 Newtons. The current from the river is equal to 496 Newtons.
This will be the overall effect of the forces on his kayak
What is the kayak will move forward with a force of 2129 newtons?
(Imaging the picture with 4 batteries with light bulbs attached)
Which battery was connected to a circuit CORRECTLY wired in a series?
What is battery C?
If a force of 6 newtons to the right and a force of 6 newtons to the left are acting upon a ball, the ball will?
What is continue with the same velocity?
