Building with Legos, magnetic tiles, or other construction toys is another activity where students naturally apply computational thinking. As they design and construct their creations, they break down complex s
In our daily life, you may think of vectors being used to represent the velocity of an aircraft, where both the speed and the direction of movement of the aircraft are to be known. Electromagnetic induction involves an interplay of electric forces and magnetic forces. ...
Compute magnetic flux density for an object: 1m 1A Helmholtz coil Compute the maximum force of a spring: spring maximum force更多示例 运输 Examine information about a variety of transportation systems, which are used to move both people and things across town or around the world. Get information...
The direction of the middle finger should now indicate the direction of the magnetic force. Note that these three are perpendicular or at 90∘-angle with each other. A current-carrying loop in an external magnetic field. This is the view when facing the loop....
Superpositionrefers to qubits that are in all possible states at once until they are measured. Think of a qubit as an electron in a magnetic field. The electron's spin might be either in alignment with the field, known as aspin-up state, or opposite to the field, known as aspin-down...
Learn about polymers, their properties, their examples, and their applications in life. See their products, what they are made of, and how they are...
Electromagnetic Inductionis the phenomenon due to which an emf is induced in a conducting loop, placed in a magnetic field when there is a change in the magnetic flux associated with the loop. It is also the phenomenon due to which an emf is induced across the ends of a conductor when it...
Window light is also nice and often allows for a bit more drama. Experiment by standing near the window and capturing photos with different lighting angles. Notice how your images change as you position yourself so the light streams in from off to the side, from directly in front of you, ...
It is also known as the electromagnetic force balance and has widely replaced the mechanical or single pan balance. The passing current generates a magnetic force that balances the load placed on the balance pan. Thus, the current required is directly proportional to the object’s mass on the ...
