The main use is for the measurement of temperature by means of thermocouples; there are some applications to electric power generation. See Thermocouple, Thermoelectricity 4. The photovoltaic effect, in which the absorption of light (or, more generally, electromagnetic radiation) in a semiconductor ...
And so the RHR-2 requires that I be counterclockwise, which in turn means the top of the rod is positive as shown.Motional emf also occurs if the magnetic field moves and the rod (or other object) is stationary relative to the Earth (or some observer). We have seen an example of ...
8.This means that the magnetic flux through the loops in the coil changes over time, which is what induces anemf. 这意味着通过线圈中的环路的磁通量会随着时间而变化,这就是感应 的原因。 「Crash Course Physics 速成课物理」评价该例句:好评差评指正 ...

Ionizing means creating an "ion" form of a molecule - that is, detaching an electron, converting the molecule to an "ionized" form with a different electrical charge. Ionizing radiation is known to be dangerous to humans and other animals. ...

Well, let's see. We have an induced current, that's I IND, that is in the presence of a magnetic field. So that means that there's actually going to be a magnetic force here, and we want the sum of those forces to equal 0. So remember that the strength of this magnetic field ...
Bonferroni-adjusted pairwise comparisons were performed for multiple comparisons of the means between the groups. EMF effect would be indicated by a significant main effect for intervention. One-way ANOVA (for normally distributed data) were used to analyze other dependent variables, and the Tukey ...
